rename "xcpu" back to "cpu" now that the conflicting global variable
has been renamed out of the way. this also fixes some cases
where references to the local variable "cpu" had not been renamed
and thus were accidentally referring to the former global "cpu".
caches, merge together pool_drain_start() and pool_drain_end() into
bool pool_drain(struct pool **ppp);
"bool" value indicates whether reclaiming was fully done (true) or not (false)
"ppp" will contain a pointer to the pool that was drained (optional).

GCC can generate bogus dwarf attributes with DW_AT_byte_size set to 0xFFFFFFFF.
See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35998 .
GCC is currently doing this for external/bsd/tmux/dist/compat/imsg-buffer.c:
readelf -a --debug-dump imsg-buffer.o
...
<2><6e3>: Abbrev Number: 32 (DW_TAG_union_type)
<6e4> DW_AT_byte_size : 0xffffffff
<6e8> DW_AT_decl_file : 1
<6e9> DW_AT_decl_line : 229
<6ea> DW_AT_sibling : <0x705>
This resulted in ctfconvert generating a faulty CTF entry which then caused the
segfault in ctfmerge.
The fix has ctfconvert check for the bogus 0xFFFFFFFF value and works around it.
It also adds some protection to ctfmerge to avoid the segfault and fail
more gracefully if the error should occur in the future.
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
for vdev. This makes ztest survive ztest_vdev_LUN_growth test. Replace dummy
VOP_GETATTR with vn_getattr routine which reset vp_size and vattr_size accordingly
to reality.
