bug#18230: Removing support for DJGPP < 2.02

Given that DJGPP 2.02 was released in 1998, may I remove the two files
which are added to support earlier releases, that is:

msdos/is_exec.c
msdos/sigaction.c

? They come with a licensing exception, its explanation, and notes in other
files (e.g. admin/notes/copyright) that maintainers not concerned with the
MS-DOS port may have to read. This therefore removes a small bit of
unnecessary clutter. My patch touches the following files:

admin/authors.el
admin/notes/copyright
etc/PROBLEMS (the problems no longer exist!)
make-dist
msdos/INSTALL
msdos/README

as well as the two removed files. No code (other than make-dist) is
affected, as the method of using them was entirely reliant on manual
intervention (the instructions said to compile and link the files into the
Emacs executable).

OK.  But if we are dropping v2.01, please also remove the code in
msdos.c and dosfns.c, and also in msdos/sed2v2.inp, that caters to
v2.01 and older versions.

We should also mention in msdos/INSTALL than only version 2.02 and
later are supported.

Finally, config.bat should have its test of the DJGPP version updated
to fail v2.01 and older versions.

TIA

Sorry, I had spotted that, but read a "<" as a "<=", so was intending to
address it separately. I'll address it in the same patch.

Will do.
