Add wrappers around fopen(), use mmap on glibc Add wrappers to fopen(). The intent is to replace references to FILE * with an internal structure which can also cache things like the filename and, when needed, the full pathname and checksums. Also, add the "m" flag if we are compiling for glibc, for speed. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

Move the output format macros into the macros.pl mechanism 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.

codeview: Look up %include path when determining files to hash. 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.
