Parsing of package source files

This module exposes two functions, [[parse_f_source]] and [[parse_c_source]], which perform a rudimentary parsing of fortran and c source files in order to extract information required for module dependency tracking.

Both functions additionally calculate and store a file digest (hash) which is used by the backend (fpm_backend) to skip compilation of unmodified sources.

Both functions return an instance of the srcfile_t type.

For more information, please read the documentation for each function:

• [[parse_f_source]]
• [[parse_c_source]]
