Properly init 'fd' and avoid closing a random fd later.
Fix format string usage
Dont return NULL in a function returning void
constify task names
constify commonStruct descriptors
Unifdef __STDC__
Remove xes.h.

The rest of the xes subsystem was already removed 8 years ago.
constify write buffer arguments
Remove unused variable
Don't cast H2TIMESPEC to struct timespec

This breaks the reason why H2TIMESPEC was introduced.
Update CHANGELOG
Add COPYING to distfiles
Fix compilation warning
Hack the taskSuspend() regress test to make it success.
