Description
The zzip_disk_entry_to_data function augments the other zzip_disk_entry_* helpers: here we move
a disk_entry pointer (as returned by _find* functions) into a pointer to
the data block right after the file_header. Only disk->buffer would be
needed to perform the seek but we check the mmapped range end as well.
The zzip_disk_entry_to_file_header function does half the job of zzip_disk_entry_to_data where it
can augment with zzip_file_header_to_data helper from format/fetch.h
The zzip_disk_entry_strdup_name function is a big helper despite its little name: in a zip file the
encoded filenames are usually NOT zero-terminated but for common usage
with libc we need it that way. Secondly, the filename SHOULD be present
in the zip central directory but if not then we fallback to the filename
given in the file_header of each compressed data portion.
The zzip_disk_entry_strdup_comment function is similar creating a reference to a zero terminated
string but it can only exist in the zip central directory entry.
