3d32d4a7c9 Export the whole thread name in kinfo_proc
kinfo_proc::ki_tdname is three characters shorter than
thread::td_name.  Add a ki_moretdname field for these three
extra characters.  Add the new field to kinfo_proc32, as well.
Update all in-tree consumers to read the new field and assemble
the full name, except for lldb's HostThreadFreeBSD.cpp, which
I will handle separately.  Bump __FreeBSD_version.

af463464cf Fix a kernel panic in DTrace's rw_iswriter subroutine.
On FreeBSD the sense of rw_write_held() and rw_iswriter() were reversed,
probably due to a cut and paste error. Using rw_iswriter() would cause
the kernel to panic.

stack_machdep.c is compiled if either of the DDB or STACK options is
specified, but stack_save_td_running() isn't useable from DDB. Moreover,
stack_save_td_running() works by raising an NMI on the CPU running the
target thread, and the corresponding handler is compiled only if STACK is
configured.

e0d70fc1dc libdtrace: Don't use a read-only handle for enumerating pid probes.
Enumeration of return probes involves disassembling subroutines in the
target process, and ptrace(2) is currently used to read from the target
process. libproc could read from the backing file instead to avoid this
problem, but in the common case libdtrace will have a writeable handle
on the process anyway. In particular, a writeable handle is needed to list
USDT probes, and libdtrace will cache such a handle for processes that it
controls via dtrace -c and -p.

This change adds some handling for the equivalent of Solaris' PGRAB_*

pseudo-terminal and end up blocking while writing to standard output.

c156354ff8 libproc: Cache symbol tables for mapped objects upon access.
Extend the file handle cache entries to include symbol tables as well. An
index is used to implement binary search by symbol value. Lookups by
name are comparatively rare and are thus still implemented with a linear
search, but support for a binary search by name would be straightforward
to add if needed.

d42df2a447 libproc: Match prefixes when looking up mapped object by name.
When looking up an object by name, allow prefix matches if no direct match
is found. This allows one to, for example, match libc entry probes with:

 # dtrace -n 'pid$target:libc.so::entry' -c ./foo

instead of requiring "libc.so.7" or a glob.

Also remove proc_obj2map() as it currently just duplicates the
functionality of proc_name2map(). It's supposed to take a Solaris
link-map ID as a paramter, but support for this isn't implemented and
isn't required to support DTrace's pid provider.

As of r278658 libproc looks for debug files under /usr/lib/debug and will

- Check for a .gnu_debuglink section and use the file name specified
  there if one is present.
- Validate external debug files with the CRC in the .gnu_debuglink
  section so as to avoid using stale or corrupt debug files.
- Search for debug files in the directory containing the referencing
  object or in the .debug subdirectory, as GDB does.

1175b23f77 Rework syscall structure lookups.
Avoid always using an O(n^2) loop over known syscall structures with
strcmp() on each system call.  Instead, use a per-ABI cache indexed by
the system call number. The first 1024 system calls (which should cover
all of the normal system calls in currently-supported ABIs) use a flat array
indexed by the system call number to find system call structure.  For other
system calls, a linked list of structures storing an integer to structure
mapping is stored in the ABI.  The linked list isn't very smart, but it
should only be used by buggy applications invoking unknown system calls.

This also fixes handling of unknown system calls which currently trigger
a NULL pointer dereference.
