Remove lib-src/test-distrib.c and related

Browse Source 
The class of problems that this was designed to detect, namely .elc
files getting corrupted by being passed around by email via uuencode
or somesuch, has not been a relevant concern for many years.

* lib-src/test-distrib.c, lib-src/testfile: Remove.

* lib-src/Makefile.in (DONT_INSTALL): Remove test-distrib.
(test-distrib${EXEEXT}): Remove rule.

* make-dist: Do not distribute lib-src/testfile.

* admin/quick-install-emacs (AVOID): Remove testfile and test-distrib.

* INSTALL, etc/PROBLEMS, admin/notes/unicode:
Remove references to test-distrib and testfile.

This can be because the .elc files have been garbled. Do not be
fooled by the fact that most of a .elc file is text: these are
binary files and can contain all 256 byte values.
If you have a copy of Emacs whose .elc files have been damaged in this
way, you should be able to fix it by using:
make bootstrap
to regenerate all the .elc files.
*** temacs prints "Pure Lisp storage exhausted".
This means that the Lisp code loaded from the .elc and .el files
