1f1ed24cc5 crashinfo: add "batch" mode and use it during boot
In batch mode, most messages go into the core.txt.N file instead of stdout.

73ad3fb536 Add a new GDB_LIBEXEC option to install gdb and kgdb to /usr/libexec.
When this option is enabled, only gdb and kgdb are installed to
/usr/libexec for use by crashinfo(8). Other bits of GDB such as
gdbserver and gdbtui are not installed. For this option to be
effective, GDB must be enabled.

Rework r317094 to re-enable GDB on all platforms but enable
GDB_LIBEXEC on platforms for which the GDB in ports is a superset of
functionality.

241cf416c9 Update crashinfo to work with newer gdb from ports.
If gdb from ports is installed, use it instead of the base system gdb
to extract variables from a kernel.  Note that base gdb and ports gdb
do not support the same options for invoking a single command in batch
mode, so a wrapper shell function is used.  In addition, prefer kgdb
from ports when generating a backtrace if present.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

7ad50a360b Improve multi-line kernel ident parsing
Instead of blindly grabbing the line with 'Version string' and the
following one from the core info file, take all lines after 'Version
string' until the one one that matches the field format in the core info
file.  This provides compatibility with VendorBSD modifications that have
a different kernel ident format.

9decd44681 Teach crashinfo(8) to look at the currently running kernel (based on the
kern.bootfile sysctl).  Prior to this commit, crashinfo(8) only looks at
/boot/*/kernel; this includes the usual places where kernels reside, so
for most systems this will have no effect.

a37f97161c Add a script to perform simple analysis of a crash dump (either a full
dump or minidump).  When the script is run, it generates a text file
containing the output of several commands run againt the core dump such
as kgdb (stack trace), ps, netstat, vmstat, iostat, dmesg, and fstat.
