Add new output-only formats and Define constants for the different plist formats

This commit introduces constants for the different plist formats,
and adds 3 new human-readable output-only formats:
- PLIST_FORMAT_PRINT: the default human-readable format
- PLIST_FORMAT_LIMD: "libimobiledevice" format (used in ideviceinfo)
- PLIST_FORMAT_PLUTIL: plutil-style format

Also, a new set of write functions has been added:
- plist_write_to_string
- plist_write_to_stream
- plist_write_to_file

Plus a simple "dump" function:
- plist_print

See documentation for details.
