ANSI-fy lex

while here remove the unused function action_m4_define() and two
unused variables: `opt' in scanopt_err() and `num' in filter_fix_linedirs()

ok miod@

spelling fixes; from paul tagliamonte
amendments to his diff are noted on tech

burn down all the gratutious alloca() compatability that autofuck injected
to ensure nobody uses alloca by accident.

remove the LGPL gettext.h since we aren't using it anyway.
spotted by nicm

Replace Char (defined as unsigned char) with u_char.

ok tedu@

flex_alloc and flex_free are nothing more than malloc and free, so replace
them with the real functions so as to not trick people into thinking they
are special

it should be safe to assume the presence of memset these days instead of
implementing a local version.

remove VMS and MSDOS support

Update flex from ancient 2.5.4 to the recent 2.5.39.
This work was all done by Serguey Parkhomovsky. Thanks.
Some changes from upstream:
* Removed autotools cruft/localization/texinfo manual/etc
* Kept the old manpage, as the new manpage is content-free
* Used safe string handling functions and fixed several compiler warnings
* pledge(2). Flex 2.5.39 now forks/execs its filter chains and needs proc
exec in addition to what was previously pledged
* Removed register keyword from all variable declarations
* renamed parse.c, parse.h, scan.c, skel.c with init prefix so compiling
flex outside of obj by accident wouldn't clobber the bootstrap files
* Minor fixes (spelling, accessing buf[strlen(buf) - 1] for zero-length
strings in initscan.c/scan.l, etc) that were already in our tree

This is a huge change, so it's going in the tree code bomb style.
I'm not excited about the growth in complexity (like now running m4
to _post_ process lexers) but hopefully this will be a one time update
and we will now take "ownership" of the code.

Some of these large so easy to contain, with "stdio rpath".
ok doug

bring some standard C++ fixes, mostly from NetBSD.
get isatty proto from the right place.
avoid malloc.h

okay otto@, millert@
