This commit removes the existing tar test cases that simply call the
generic test case function with several different paths with generic
test case source files that are parameneterized via the pro-processor.
For each tar archive, a separate test case is generated.
On the one hand, this reduces the test source code to practically
nothing. On the other hand, a test binary is generated for every
distinct test case, instead of one per group and we get more detailed
insights if something goes wrong.

Many of the patterns tested are very repetetive. This commit moves the
two common test cases out into helper functions and uses them for
the test cases.

This commit adds a few macros and helper functions for the unit test
programs. Those are used instead of asserts to provide more fine
grained diagnostics on the one hand and on the other hand because
they also work if NDEBUG is defined, unlike asserts that get eliminated
in that case.

In most cases, including unistd.h and fcntl.h was a left over anyway.
In the cases where it was not, move it to compat.h.

This only exists for tar2sqfs. Move the sparse file map to libtar
and add the ability to do this into the stind sqfs_file_t abstraction,
so it acts like a normal file but internally stitches the data
together from the sparse implementation.

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.

This commit broadly does the following things:
- Rename and move the sparse mapping structure to libutil
- Add a function to the data writer for writing condensed versions
of sparse files, given the mapping.
- This shares code with the already existing function for regular
files. The shared code is moved to a common helper function.
- Add support to tar2sqfs for repacking sparse files.
