Offering to add a new line at the end of the buffer didn't consider if
the user pressed C-g. Now it does.

This diff moves the check for a newline at the end of a buffer (when
saving it) earlier. This means data doesn't 'disappear' from the file
on disk while the user answers 'yes' or 'no'.

Add dired-find-alternate-file.

Fix opening dired from the command line. Incorrect cursor placement
and make the error more useful when there is a problem opening a
directory. Reported by and ok jasper@

Check to see if the file to be opened is a directory as soon as is
feasible. Currently, mg does this check much later on which means some
functions (e.g showbuffer()) are called multiple times. This fixes the
location of the cursor when opening a directory using filevisit,
findvisitalt and poptofile. ok jasper@

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.

This diff allows the user to decide what to do with buffers that
experience write errors during C-x C-c (exiting mg). Emacs stops the
exiting process when it encounters problem buffers and lets the user
decide what to do, currently mg continues exiting and the contents of
these buffers are lost. This diff bring mg more into line with emacs.

Removing this 'if' statement allows dired buffers to not have their
forward and backward line pointers pointing to the same line, causing
mg to spin when asked to split the window. This happens if a directory
is opened via the command line sequentially first, and other windows
need to opened afterwards (for other files).

Since the information within this 'if' statement is updated later for
files and directories I can see no problem with removing this. No
regressions viewable either.

Remove static FILE pointer used for handling files in fileio.c. Pass
by reference instead. This allows the mg startup file to open other
files without unexpected things happening.
