b1f92fa229 META MODE: Update dependencies with 'the-lot' and add missing directories.
This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so.  A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR.  These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package.  The current implementation of targets/ is
very unmaintainable.

Currently rescue/rescue and sys/modules are still not connected.

cf990407e1 Update dependencies after r291406 added libelf to libkvm.
Unfortunately filemon/meta mode tracks all indirect dependencies here
since ld(1) is reading libelf when linking in libkvm.  Churn would be
reduced if this was able to be limited to direct dependencies.

7f911abe54 Add support to libkvm for reading vmcores from other architectures.
- Add a kvaddr_type to represent kernel virtual addresses instead of
  unsigned long.
- Add a struct kvm_nlist which is a stripped down version of struct nlist
  that uses kvaddr_t for n_value.
- Add a kvm_native() routine that returns true if an open kvm descriptor
  is for a native kernel and memory image.
- Add a kvm_open2() function similar to kvm_openfiles().  It drops the
  unused 'swapfile' argument and adds a new function pointer argument for
  a symbol resolving function.  Native kernels still use _fdnlist() from
  libc to resolve symbols if a resolver function is not supplied, but cross
  kernels require a resolver.
- Add a kvm_nlist2() function similar to kvm_nlist() except that it uses
  struct kvm_nlist instead of struct nlist.
- Add a kvm_read2() function similar to kvm_read() except that it uses
  kvaddr_t instead of unsigned long for the kernel virtual address.
- Add a new kvm_arch switch of routines needed by a vmcore backend.
  Each backend is responsible for implementing kvm_read2() for a given
  vmcore format.
- Use libelf to read headers from ELF kernels and cores (except for
  powerpc cores).
- Add internal helper routines for the common page offset hash table used
  by the minidump backends.
- Port all of the existing kvm backends to implement a kvm_arch switch and
  to be cross-friendly by using private constants instead of ones that
  vary by platform (e.g. PAGE_SIZE).  Static assertions are present when
  a given backend is compiled natively to ensure the private constants
  match the real ones.
- Enable all of the existing vmcore backends on all platforms.  This means
  that libkvm on any platform should be able to perform KVA translation
  and read data from a vmcore of any platform.

114350b9de Replace DPSRCS that work fine in SRCS.
This is so that 'make depend' is not a required build step in these
files.

DPSRCS is overall unneeded.  DPSRCS already contains SRCS, so anything
which can safely be in SRCS should be.  DPSRCS is mostly just a way to
generate files that should not be linked into the final PROG/LIB.  For
headers and grammars it is safe for them to be in SRCS since they will
be excluded during linking and installation.

The only remaining uses of DPSRCS are for generating .c or .o files that
must be built before 'make depend' can run 'mkdep' on the SRCS c files
list.  A semi-proper example is in tests/sys/kern/acct/Makefile where a
checked-in .c file has an #include on a generated .c file.  The
generated .c file should not be linked into the final PROG though since
it is #include'd.  The more proper way here is just to build/link it in
though without DPSRCS.  Another example is in sys/modules/linux/Makefile
where a shell script runs to parse a DPSRCS .o file that should not be
linked into the module.  Beyond those, the need for DPSRCS is largely
unneeded, redundant, and forces 'make depend' to be ran.  Generally,
these Makefiles should avoid the need for DPSRCS and define proper
dependencies for their files as well.

An example of an improper usage and why this matters is in usr.bin/netstat.
nl_defs.h was only in DPSRCS and so was not generated during 'make all',
but only during 'make depend'.  The files including it lacked proper
depenencies on it, which forced running 'make depend' to workaround that
bug.  The 'make depend' target should mostly be used for incremental build
help, not to produce a working build.  This specific example was broken in
the meta build until r287905 since it does not run 'make depend'.

The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS:
SRCS:M*.h' when there is no .depend file.

b791fbe630 META MODE: Don't create .meta files when symlinking sources into the obj directory.
Tracking these leads to situations where meta mode will consider the
file to be out of date if /bin/sh or /bin/ln are newer than the source
file.  There's no reason for meta mode to do this as make is already
handling the rebuild dependency fine.

8b2b71b415 Fix ld not respecting --sysroot.
ld(1) uses the /usr/libdata/ldscripts when linking. These scripts add in the
default search paths of /lib and /usr/lib via 'SEARCH_DIR("DIR")'. These
need to be prefixed by '=' so that the --sysroot flag is respected. This
is not a problem with buildworld since the TOOLS_PREFIX is baked into the
cross-ld. However it is a problem when trying to use ld(1) with --sysroot
anywhere else as it ends up still reading /lib and /usr/lib despite --sysroot.

The default --sysroot (TARGET_SYSTEM_ROOT) is '/' for /usr/bin/ld.

I found this while building with META MODE with uses only --sysroot with
/usr/bin/ld, and found that libraries that I had not built in its sysroot
directory were leaking in. This didn't happen with ports binutils either.  This
would also impact external compiler support.

0cc887023b Avoid warning race with creating 'ldscripts' directory during build.
In r204548 the 'rm -f ldscripts' was added likely due to reading the
conditional as 'else it is a file'.  That seems unlikely though and
the more likely case is just that the directory hasn't been created yet.

Because this races with ,ssother scripts, use 'mkdir -p' which is a minimal
modification vs upstream to avoid the warning of 'File exists' if another
script creates it first.  This could replace the 'test -d' as well but
then it's more unneeded change to the upstream script.

24df1f7e7f Replace most of the beforeinstall: hack with FILES mechanism.
This now generates the files into the OBJDIR as needed.  Some of the files
are installed directly from the src directory.  Files which are generated
from the src directory are renamed to .in to generate them and avoid
colliding with the checked-in file when CURDIR=OBJDIR.

The remaining beforeinstall: handling still needs to be reworked as it does
not work well with staging for packaging.

df66ebeba3 When XSAVE support was added on amd64, the FPU save area was moved
out of 'struct pcb' and into a variable-sized region after the
structure. The kgdb code currently only reads the pcb. It does not
read in the FPU save area but instead passes stack garbage as the
FPU's saved context. Fixing this would mean determining the proper
size of the area and fetching it. However, this state is not saved
for running CPUs in stoppcbs[], so the callback would also have to
know to ignore those pcbs. Instead, just remove the call since it is
of limited usefulness. It results in kgdb reporting the state of the
FPU/SIMD registers in userland, not their current values in the kernel.
In particular, it does not report the correct state for any code in
the kernel which does use the FPU and would report incorrect values
in that case.

- fully compatible with RCS 5.9 ident.
- passes all ident test from GNU RCS 5.9 test suite

This version has support for: svn extension for the Keyword id (double colon and

Différences with GNU RCS ident:
- no long options as found in GNU RCS 5.9 (but not commented there).
- '-V' reports nothing but has been added for compatibility.
