adbb8027be Remove PIPE_BUF Linux-specific code 
Fixes BZ #12723

The variable pipe buffer size does nothing to the value of PIPE_BUF,
since the number of bytes that are atomically written is still
PIPE_BUF on Linux.

e69804d14e Use long wherever possible in mpa.c 
Using long throughout like powerpc does is beneficial since it reduces
the need to switch to 32-bit instructions.  It gives a very minor
performance improvement.

6ff444c418 unify xmalloc prototypes & friends 
These prototypes are duplicated in many places.  Add a dedicated
header for holding prototypes for program-specific functions to
avoid that.

ba384f6ed9 C++11 thread_local destructors support 
This feature is specifically for the C++ compiler to offload calling
thread_local object destructors on thread program exit, to glibc.
This is to overcome the possible complication of destructors of
thread_local objects getting called after the DSO in which they're
defined is unloaded by the dynamic linker.  The DSO is marked as
'unloadable' if it has a constructed thread_local object and marked as
'unloadable' again when all the constructed thread_local objects
defined in it are destroyed.
