Add a non-interactive version of query-replace-regexp function called
replace-regexp. Unfortunately query-replace-regexp can't be used in a
startup file.

Avoid running out of memory with query-replace-regex ^

Choosing ! (replace rest) never advances beyond the current line
and keeps inserting the replacement test, and mg eventually runs
out of memory

Patch from Mark Willson with minor stylistic tweaks.

Looks good to Hiltjo Posthuma who would have preferred making forward
replacing on empty lines work. Mark argued that this makes it behave
consistently with the current behaviour when searching for ^ and the
point at the beginning of a non-empty line in which case the cursor does
not move either.

Avoid NULL deref in regexec when searching for empty lines.

Report & tweak from Hiltjo Posthuma

Present the default choice before the colon in prompts. Matches GNU Emacs
behavior.

Clean up the includes in mg.
This does the following:
Moves all POSIX headers from sysdef.h into the individual .c files so that
each file now only includes what it needs. All headers are properly sorted.
Moves the remainder of sysdef.h to other files (mostly def.h) and deletes
sysdef.h now that it's no longer contains anything.
Tweak a comment that references sysdef.h so that it no longer does that.

while here, rename re_buff accordingly for consistency.

It volates style(9), but in mg, #include"def.h" goes first. 'twas the way it was built. no binary change here. confirmed by lum@, tested by Henri Kemppainen

Rename the header line of a buffer to b_headp, from the remarkably
unintuitive b_linep. No binary change.

Make Window Flags more mnemonic (and less dumb); i.e.
WFHARD -> WFFULL (Redraw full window)
WFFORCE -> WFFRAME (Reframe window).
No binary change

Clean up eread handling in mg. (basically, fallout from the 'enter often
means abort' behaviour added during the hackathon). Eliminates
redundant ereply function, fixes miscellaneous cores when aborting,
and move a number of assumed pathnames into the prompt text, since
they are used there anyway. All changes consistent with emacs behavior

Three more ereply that should be ereads. This fixes henning's "replace

if functions permits null reply from minibuffer, use eread (with
EFNUL), not ereply.

This is a no binary change which does:

- spelling, punctuation fixes
- variable declaration lineup
- use parentheses for return and sizeof
- K&R function declarations -> ANSI
- other minor code beau

stage 1 of the infinite minibuffer work - add support for on the fly
buffer reallocation in veread(). This commit only changes the API.
All the buffers have exactly the same bounds as before for now
