The output of "locale charmap" is identical to the result of
nl_langinfo (CODESET) for any given locale. The logic for returning the
codeset was very simplistic. It just returned portion of the locale name
after the period (e.g. en_FR.ISO8859-1 returned "ISO8859-1").
When softlinks were added to locales, this broke. e.g.:
en_US returned ""
en_FR.UTF8 returned "UTF8"
en_FR.UTF-8 returned "UTF-8"
zh_Hant_HK.Big5HKSCS returned "Big5HKSCS"
zh_Hant_TW.Big5 returned "Big5"
es_ES@euro returned ""
In order to fix this properly, the named locale cannot be used to
determine the encoding. This information was almost available in the
rune data. Unfortunately, all the single byte encodings were listed
as "NONE" encoding.
So I adjusted localedef tool to provide more information about the
encoding. For example, instead of "NONE", the LC_CTYPE used by
fr_FR.ISO8859-15 is now encoded as "NONE:ISO8859-15". The locale
handlers now check if the first four characters of the encoding is
"NONE" and if so, treats it as a single-byte encoding.
The nl_langinfo handling of CODESET was adjusting accordingly. Now the
following is returned:
en_US returns "ISO8859-1"
fr_FR.UTF8 returns "UTF-8"
fr_FR.UTF-8 returns "UTF-8"
zh_Hant_HK.Big5HKSCS returns "Big5"
zh_Hant_TW.Big5 returns "Big5"
es_ES@euro returns "ISO8859-15"
as before, "C" and "POSIX" locales return "US-ASCII". This is a big
improvement. The result of nl_langinfo can never be a zero-length
string and it will always exclusively one of the values of the
character maps of /usr/src/tools/tools/locale/etc/final-maps.

FreeBSD extended ctypes to include numbers (e.g. isnumber()) but never
actually implemented it. The isnumber() function was equivalent to the
isdigit() function in every case.
Now that DragonFly's ctype source files have number definitions, the
number ctype can finally be implemented. It's given a new flag _CTYPE_N.
The isalnum() and iswalnum() functions have been changed to use this
flag rather than the _CTYPE_D digit flag.
While isalnum(), isnumber(), and their wide equivalents now return
different values in locale cases, the ishexnumber() and iswhexnumber()
functions are unchanged. They are still aliases for isxdigit() and
iswxdigit().
Also change ctype.h for isdigit and isxdigit to use sbistype like the
other functions.

This is to make the Makefile more easily extendable for new ABIs.
This also makes several other subtle changes:
- The build now is given a list of ABIs to use based on the MACHINE_ARCH or
MACHINE_CPUARCH. These ABIs have a related path in sys/ that is used
to generate their syscalls. For each ABI to build check for a
ABI.c, MACHINE_ARCH-ABI.c, or a MACHINE_CPUARCH-ABI.c. This matches
the old behavior needed for archs such as powerpc* and mips*.
- The ABI source file selection allows for simpler assignment of common
ABIs such as "fbsd32" from sys/compat/freebsd32, or cloudabi64.
- Expand 'fbsd' to 'freebsd' everywhere for consistency.
- Split out the powerpc-fbsd.c file into a powerpc64-freebsd32.c to be more
like the amd64-freebsd32.c file and to more easily allow the auto-generation
of ABI handling to work.
- Rename 'syscalls.h' to 'fbsd_syscalls.h' to lessen the ambiguity and
avoid confusion with syscall.h (such as in r288997).
- For non-native syscall header files, they are now renamed to be
ABI_syscalls.h, where ABI is what ABI the Makefile is building.
- Remove all of the makesyscalls config files. The "native" one being
name i386.conf was a long outstanding bug. They were all the same
except for the data they generated, so now it is just auto-generated
as a build artifact.
- The syscalls array is now fixed to be static in the syscalls header to
remove the compiler warning about non-extern. This was worked around
in the aarch64-fbsd.c file but not the others.
- All syscall table names are now just 'syscallnames' since they don't
need to be different as they are all static in their own ABI files. The
alternative is to name them ABI_syscallnames which does not seem
necessary.

CloudABI has approximately 50 system calls that do not depend on the
pointer size of the system. As the ABI is pretty compact, it takes
little effort to each truss(8) the formatting rules for these system
calls. Start off by formatting pointer size independent system calls.
Changes:
- Make it possible to include the CloudABI system call definitions in
FreeBSD userspace builds. Add ${root}/sys to the truss(8) Makefile so
we can pull in <compat/cloudabi/cloudabi_syscalldefs.h>.
- Refactoring: patch up amd64-cloudabi64.c to use the CLOUDABI_*
constants instead of rolling our own table.
- Add table entries for all of the system calls.
- Add new generic formatting types (UInt, IntArray) that we'll be using
to format unsigned integers and arrays of integers.
- Add CloudABI specific formatting types.

This change adds the bits that are necessary to fetch system call
arguments and return values from trapframes for CloudABI. This allows us
to properly print system calls with the right name. We need to make sure
that we properly convert error numbers when system calls fail.
We still need to improve truss to pretty-print some of the system calls
that have flags.

reliable since this is what the kernel depends on anyway and is also
simpler.
integer. Fix the argument decoding to treat this as a quad instead of an
int. This includes using QUAD_ALIGN and QUAD_SLOTS as necessary. To
continue printing IDs in decimal, add a new QuadHex argument type that
prints a 64-bit integer in hex, use QuadHex for the existing off_t arguments,
repurpose Quad to print a 64-bit integer in decimal, and use Quad for id_t
arguments.
This fixes the decoding of wait6(2) and procctl(2) on 32-bit platforms.
probably fallout from the removal of the extra padding argument before
off_t in 7. However, that padding still exists for 32-bit powerpc, so
use QUAD_ALIGN.
- Fix QUAD_ALIGN to be zero for powerpc64. It should only be set to 1
for 32-bit platforms that add padding to align 64-bit arguments.
- Refactor the interface between the ABI-independent code and the
ABI-specific backends. The backends now provide smaller hooks to
fetch system call arguments and return values. The rest of the
system call entry and exit handling that was previously duplicated
among all the backends has been moved to one place.
- Merge the loop when waiting for an event with the loop for handling stops.
This also means not emulating a procfs-like interface on top of ptrace().
Instead, use a single event loop that fetches process events via waitid().
Among other things this allows us to report the full 32-bit exit value.
- Use PT_FOLLOW_FORK to follow new child processes instead of forking a new
truss process for each new child. This allows one truss process to monitor
a tree of processes and truss -c should now display one total for the
entire tree instead of separate summaries per process.
- Use the recently added fields to ptrace_lwpinfo to determine the current
system call number and argument count. The latter is especially useful
and fixes a regression since the conversion from procfs. truss now
generally prints the correct number of arguments for most system calls
rather than printing extra arguments for any call not listed in the
table in syscalls.c.
- Actually check the new ABI when processes call exec. The comments claimed
that this happened but it was not being done (perhaps this was another
regression in the conversion to ptrace()). If the new ABI after exec
is not supported, truss detaches from the process. If truss does not
support the ABI for a newly executed process the process is killed
before it returns from exec.
- Along with the refactor, teach the various ABI-specific backends to
fetch both return values, not just the first. Use this to properly
report the full 64-bit return value from lseek(). In addition, the
handler for "pipe" now pulls the pair of descriptors out of the
return values (which is the true kernel system call interface) but
displays them as an argument (which matches the interface exported by
libc).
- Each ABI handler adds entries to a linker set rather than requiring
a statically defined table of handlers in main.c.
- The arm and mips system call fetching code was changed to follow the
same pattern as amd64 (and the in-kernel handler) of fetching register
arguments first and then reading any remaining arguments from the
stack. This should fix indirect system call arguments on at least
arm.
- The mipsn32 and n64 ABIs will now look for arguments in A4 through A7.
- Use register %ebp for the 6th system call argument for Linux/i386 ABIs
to match the in-kernel argument fetch code.
- For powerpc binaries on a powerpc64 system, fetch the extra arguments
on the stack as 32-bit values that are then copied into the 64-bit
argument array instead of reading the 32-bit values directly into the
64-bit array.
