Text subtitles packets are not 0-terminated (and if they are,
it is handled by the recoding process since 0 is a valid
Unicode code point). The terminating 0 would overwrite the
last payload octet.

OTOH, packets must be 0-padded.

Fix a problem reported in trac ticket #2431.

particular behaviour of the FPU will get in the way.
Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference).

The gcov/lcov are a common toolchain for visualizing code coverage with
the GNU/Toolchain. The documentation and implementation of this
integration was heavily inspired from the blog entry by Mike Melanson:
