Junio C Hamano 762655010d Merge branch 'js/async-thread'
* js/async-thread:
  fast-import: die_nicely() back to vsnprintf (reverts part of ebaa79f)
  Enable threaded async procedures whenever pthreads is available
  Dying in an async procedure should only exit the thread, not the process.
  Reimplement async procedures using pthreads
  Windows: more pthreads functions
  Fix signature of fcntl() compatibility dummy
  Make report() from usage.c public as vreportf() and use it.
  Modernize t5530-upload-pack-error.
