[GSoC] src/*.*: Convert block comments to `light' style.

Browse Source 
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.

* The correct thing to do is to use @FTC_CACHE_TRYLOOP and
* @FTC_CACHE_TRYLOOP_END in order to implement a retry loop
* that is capable of flushing the cache incrementally when
* an OOM errors occur.

* returns the appropriate OOM error code.
