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.

- Store them in a struct instead of a hacky uint64_t with magic shifts
- Split up key/value pair write function to write_key and write_value
- Move the size accounting into those functions respectively

This commit adds a reference count functionality to the string table
implementation and uses this functionality in the fstree code to
count how often each key and value is referenced by the deduplicated
Xattr blocks. This is needed to support deduplication through
out-of-band storage of xattrs.

The refactor of the xattr table grow code merged all allocation code
paths into realloc(), including the initial allocation. This means that
the xattr structure is used uninitialized. This commit makes sure the
reallocated structure is alwayes cleared.
Bug found using scan-build.

This IMO makes it somewhat easier to read and understand what's going on.
