d745c852be Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.
This means that their use is restricted to a single C file.

b5bd50ae40 Add an option to have a fail point term only execute when run by a
specified pid.  This is helpful for automated testing involving a global
knob that would otherwise be executed by many other threads.

4b7c684420 Initialize fp_location for explicitly managed fail points, and push
the parentheses around the location for simple fail points into the
location string.  This makes the print on fail point set more
consistent between the two versions.

Also fix up fail.h a little for style(9): only use one of sys/param.h
and sys/types.h, and use the existing __XSTRING() macro instead of
rolling our own.  Also fix up a few tabs on changed and nearby lines.

Lastly, since KFAIL_POINT_{BEGIN,END} are not meant for use outside
this file, just eliminate the macros entirely.

d26b794591 Move the fail_point_entry definition from fail.h to kern_fail.c, which
allows putting the enumeration constants of fail point types with the
text string that matches them.

cfeb7489c2 fail(9) support:
Add support for kernel fault injection using KFAIL_POINT_* macros and
fail_point_* infrastructure. Add example fail point in vfs_bio.c to
simulate VM buf pressure.
