Requires that config.h be included before other headers, since the macro
_FILE_OFFSET_BITS changes the definitions of things like 'struct stat'.
I chose to simply include it at the top of every C file and at
immediately after the double-inclusion guards of every header.

If write_retry fails to write everything, it is *always* an error.
This commit renames write_retry to write_data and moves error handling
into the function, making a lot of error handling code redundant.

Some experiments seem to indicate that the various GNU extensions are
more widely supported than their POSIX equivalents[1]. Possibly because
they are easier to implement and possibly because of the wide spread
use of GNU tar.
This commit replaces the PAX writer in the write_tar_header implementation
with a GNU extension based writer.
The writer is also cleaned up by removing all global state. The record
counter is moved outside into the tar2sqfs program and passed in as
function argument.

This commit attempts to split some of the monolitic tar parsing code up
into multiple functions in seperate files. Also, some code duplication
(like reading a record into memory which was implemented twice) is
removed.
