Delete obsolete /* ARGSUSED */ lint comments.

ok miod@ millert@

When it's the possessive of 'it', it's spelled "its", without the
apostrophe.

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.
ok florian@

Remove the conditional directives NO_MACRO and NO_STARTUP.
They have not compiled for numerous years.
ok kjell@ millert@

Remove the NO_HELP conditional directives. If defined, mg will not compile and
has not done so for numerous years. Not hard to fix, but just remove anyway.
ok kjell@ millert@

Add the notion of an "ephemeral" popup, so we can flag a window
for destruction at a later date. (in the process, add a window flag field)

This fixes an issue noted by maja: namely, the *completion*
window that pops up when you try to complete a filename on
buffer load would destroy any second window that you happened
to have open.

ok maja@

argh. One problem with fixing a hidden global symbol is that if you miss one,
you get no warning. Fixes an immediate core in describe-bindings.

Last round of easy delinting.

More name-clash delinting

do some silly de-linting

greedy use of typedef struct was making code harder to read; ok kjell cloder

unused variables

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

ok beck@ many, many moons ago.

Add explicit public domain notices to all public domain files.
ok millert@, deraadt@

Get rid of unused arg to complete_function_list(). Han Boetes.

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 beautification

ok henning@

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.

tested by a couple of my very helpful testers!

knf

KNF + ansi; from zyrnix (only the easy part of his diffs)

fix bad usage of strlcpy()'s return value. (made pointers point
beyond the boundaries of buffers)

ok deraadt@

Make these special buffers readonly by default. ok art@

* Move to ANSI function definitions.
* Add a whole lot of consts where I thought it made sense

no ok, but no objections either...

snprintf makes me happy

Break out function -> name mappings to an own file.
Add a possibility to dynamically extend the function table.

Give the arguments in the right order to keyname.

spaces

cinfo is const, keyname() and findbind() take buffer size to use strlcpy vs cpy+len

remove VOID. We're way beyond the point where this could build with an
ancient compiler.

Use 'fundamental_map' where 'map_table[0].p_map' or 'name_map("fundamental")'
were used.

Simplify a lot of code in the help functions.
It might be a bit more cpu-intensive now, but it shrinks the code a lot.

When a key is bound to selfinsert, it shouldn't be considered to be bound
to anything.

Add an argument to doscan which is a pointer to a KEYMAP pointer.
If that argument is not NULL, we set it to the k_prefmap of the pressed
key if there is one.
This is what most of the users of doscan did anyway, but they did it through
leaked global state.

Get rid of 'prefix' and use NULL instead.
