. By defining getcallerpc(x) as __builtin_return_address(0)
here, it becomes possible to use the Plan 9 compatible form
when compiling using GCC. The alternative is to add conditional
compilation based on the compiler identity in "cmd/8g/gsubr.c"
to distinguish between the two cases.

The "elf.h" header changes involve only comments, the released
Plan 9 C preprocessing function does not cope with multiline
comments following the #define keyword. All multiline comments
have been moved to the line above the associated definition.
Sigh! Fixing the Plan 9 compiler is not an option.
<time.h> does not exist in the Plan 9 Native library. I have
moved it from src/cmd/ld/pe.h to include/u.h. RSC correctly points
out that this copy of <u.h> is not the one used to compile the
Go release on Plan 9 platforms.

* heuristic to go farther during stack traces.
* significantly improved Linux thread handing.
acid:
* update to new libmach interface.
prof:
* use new libmach interface.
* multiple thread support (derived from Rob's copy).
* first steps toward pprof-like graphs:
keep counters indexed by pc,callerpc pairs.

* add gotype string to symbol table
* fill in gotype in 6l for known funcs/vars
* print gotype with nm -t
* load symbol and pc/ln tables into memory at magic address 0x99<<32.
* add sys.symdat() to retrieve raw bytes of symbol table
and pc/ln table.
most of this should be considered experimental
and subject to change.

use libbio instead of maintaining own buffer
libbio:
always use vlong offsets; die if off_t is too small

make sure methods end up immediately following
the struct they are methods on.
ar:
eliminate duplicate definitions from __.PKGDEF.
check that multiple .6 do not give different defs for same
exported type/var/func/const.
increase ar header name size from 16 to 64 bytes

these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.
(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)
the longs were rare enough that i don't think
it will cause integration problems.
