Rebooting 93u+m

Browse source 
This commit reboots ksh 93u+m development with a new fork based off
the archived official AT&T ast repo, master branch.

README:
- Removed. Having two READMEs is a botch.

README.md:
- Imported and edited from the archived fork,
  https://github.com/modernish/ksh -- the newer instructions will
  become applicable as I cherry-pick all the changes from there :)
    - Copy-edits.
    - Added policy and rationale for this 93u+m fork.
    - Incorporated info from old README that is still relevant.

.gitignore:
- Added.

bin/execrate:
- Removed. This one keeps changing its license header, causing git
  to show an uncommitted file. It's always re-copied anyway, and
  not for direct invocation, so, exclude and add to .gitignore.
  The source file is: src/cmd/INIT/execrate.sh

src/cmd/*,
src/lib/*:
- Remove historical baggage: everything except ksh93 and
  dependencies. This is the same stuff the ksh-community fork
  removed. I wouldn't mind keeping it, but some of this stuff
  causes build failures on macOS (and probably other systems), and
  I need to get on with fixing ksh93.
     Hopefully, we can figure out how to re-add stuff we can use
  later -- particularly the pty command (pseudo-terminal utility
  for scripting interactive sessions) which is needed for
  regression-testing the interactive shell.

[+NAME?execrate - wrapper for .exe challenged commands]
[+DESCRIPTION?\bexecrate\b runs \acommand\a after checking the \afile\a
operands for standard semantics with respect to \bwin32\b \b.exe\b
suffix conventions. This command is only needed on \bwin32\b
systems that inconsistently handle \b.exe\b across library and
command interfaces. \acommand\a may be one of \bcat\b(1), \bchmod\b(1),
\bcmp\b(1), \bcp\b(1), \bln\b(1), \bmv\b(1), or \brm\b(1).
Only the 2 argument forms of \bcp\b, \bln\b and \bmv\b are handled.
Unsupported commands and commands requiring no change are
silently executed.]
[+?With no arguments \bexecrate\b exits with status 0 if the current system
is \b.exe\b challenged, 1 if the current system is normal.]
[n:show?Show the underlying commands but do not execute.]
