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

Replace Char (defined as unsigned char) with u_char.

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.

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.

Cast arguments of ctype functions to Char, a lexism defined as unsigned
char.

Part of a larger attempt to audit ctype function argument types with
Coccinelle.

If a constant string needs a name, use a static const array instead of a
pointer or non-const array, as that minimizes the symbols, maximizes the
placement into read-only memory, and avoids warnings from gcc -Wformat=2
when they're used as format strings.
