smalls strings inside json_objects had a high overhead because dynamic
memory allocation was needed for each of them. This also meant that the
pointer needed to be updated. This is now changed so that small strings
can directly be stored inside the json_object. Note that on the regular
64 bit machines a pointer takes 8 bytes. So even without increasing
memory, we could store string up to 7 bytes directly inside the object.
The max size is configurable. I have selected up to 31 bytes (which
means a buffer of 32 including the NUL byte). This brings a 24-bytes
memory overhead, but I consider that still useful because the memory
allocator usually also has quite some overhead (16 bytes) for
dyn alloced memory blocks. In any case, the max buffer size can be
tweaked via #define.
There are now three options: JSON_C_TO_STRING_SPACED, JSON_C_TO_STRING_PLAIN and JSON_C_TO_STRING_PRETTY.
This also add a json_object_to_file_ext() that takes the same flags.
Existing output of json_object_to_json_string() is unchanged, and uses JSON_C_TO_STRING_SPACED.
Thanks fo Grant Edwards for the initial patches.
In building large systems, there are often clashes over the
preferred base type to use for bool/boolean. At least one
experience has been with a 3rd party proprietary library which
can not be changed. In that case, boolean was a synonym for
unsigned char and used widely in packed structures.
Added parse_null test. This does not change anything with how the parser handles \u0000 or null characters

omit the range check during parsing since we already have the checks when
accessing the value. There is no longer a json_type_int64, only json_type_int.
Fix some problems with parsing 0 and -0 values, and add a couple of tests.
Fix some minor compile issues on HPUX environments.
