[PATCH 0/4] getdtablesize, OPEN_MAX, etc.

[Ken Brown]

This patchset is an extension of the patch submitted here:

  https://cygwin.com/pipermail/cygwin-patches/2021q1/011060.html

That patch is included as the first patch in this set.  The change to
OPEN_MAX still needs testing to see if it has too much impact on the
performance of tcsh.

I've make a first attempt to implement the suggestion of adding a new
<cygwin/limits.h> header.  At this writing I'm not completely sure
that I fully understand the purpose of that.  My choice of which
macros to define in it might need to be changed.

Ken Brown (4):
  Cygwin: getdtablesize: always return OPEN_MAX_MAX
  Cygwin: sysconf, getrlimit: don't call getdtablesize
  Cygwin: remove the OPEN_MAX_MAX macro
  Cygwin: include/cygwin/limits.h: new header
