Trivial changes: whitespace and modes.
Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>
Change _p9strsig to return nil if tmp==nil.
Add atoi, atol, atoll. These versions call strtol/strtoll with base==0. The Unix versions use base==10.
Fighting the good fight.
Move libfmt, libutf into subdirectories of lib9. Add poll-based socket i/o to libthread, so that we can avoid using multiple procs when possible, thus removing dependence on crappy pthreads implementations. Convert samterm, acme to the single-proc libthread. Bring libcomplete, acme up-to-date w.r.t. Plan 9 distribution.
Changes for Mac OS X. Most important is stack sizes in samterm,
which were completely bogus. (Libthread used to ignore them but not anymore. Maybe we really should ignore them, but that breaks Venti, which needs *really* big stacks.)
Various tweaks to make things run on Mac OS.
The main change is the use of pthread to implement ffork.
