When assembling on Windows machines with CRLF line endings, computing
the MD5 hash from the file read in "text" mode (transforms CRLF->LF)
gives incorrect results.

The hash calculation in calc_md5 tries to open the source file via
"filename" again. For %includes, this is the file name that was
specified in the %include directive, not the actual name of the file
that was opened by the preprocessor. In other words, this fails if the
include file is not in the current working directory.
Add pp_input_fopen that uses the preprocessor include path lookup
code to resolve a file name and open it, and use that in codeview.c.

Add copyright headers to the *.c/*.h files in the main directory. For
files where I'm sure enough that we have all the approvals, I have
given them the 2-BSD license, the others have been given the "LGPL for
now" license header. Most of them can probably be changed after
auditing.

Don't use a redundant "const" for macros_t (which is const unsigned
char), since OpenWatcom doesn't like it, and I believe it is incorrect
per the C standard.
Instead of an array of strings, just have a character array; that
reduces the size of canned macros by up to 30%, and we only did
sequential access anyway.
Move the handling of "extra" macros (i.e. output format macros) into
the macros.pl mechanism. This allows us to change the format of the
internal macro store in the future - e.g. to a single byte store
without redundant pointers.
Also, stop using indicies into a long array when there is no good
reason to not just use different arrays.
Compress macros.c by representing macro directives with a single byte.
We can do this because we only use the ASCII character range inside
the standard macro files.
Note: we could save significant additional space by not having a
pointer array, and instead relying on the fact that we sweep
sequentially through the output array.
Introduce new preprocessor directives %depend and %pathsearch, and
make incbin a standard macro using these filenames. This lets us
remove the code that makes incbin search the path.
