ec766a6179 1) Remove claim of an input invariant that is only true for static mpd_t. 
Resizing is used _inside_ libmpdec functions, and it is permitted to
   change x->alloc several times while setting x->len at the end of the
   function. Therefore, for dynamic mpd_t x->alloc can _temporarily_ drop
   below x->len. Of course the final result always has x->len <= x->alloc.

   For static mpd_t this cannot happen, since resizing to a smaller
   coefficient is a no-op.

2) Remove micro optimization in mpd_switch_to_dyn(): Previously only the
   valid initialized part of the existing coefficient up to x->len was
   copied to the new dynamic memory area. Now copying does the same as
   realloc() and the entire old memory area is copied.

   The rationale for this change is that it is no longer needed to memorize
   the explanation given in 1).

f69aef747a Resize the coefficient to MPD_MINALLOC also if the requested size is below 
MPD_MINALLOC. Previously the resize was skipped as a micro optimization.

8798ad3e1e struct timeval.tv_usec is 4 bytes on 64-bit OS X as it should be, but 
is defined as an int while everyone else expects a long regardless of
length.

dc36efa368 1) Fix comment. 
2) Assert that the source operand is not special. Prevent resulting assert
   failure (harmless) by initializing flags before calling mpd_qshiftr_inplace.

3) Save a couple of instructions (mpd_zerocoeff already sets digits and len).
   Reorder initialization to match the order in the mpd_t struct.

0e41981cd5 Use abort() rather than exit() to appease tools like rpmlint. abort() is used 
in libmpdec to prevent undefined behavior if an invalid context is used. This
cannot occur for the _decimal module since user input for the context is
validated.

eac0939ddd #14416: conditionally add LOG_AUTHPRIV facility and LOG_ODELAY to syslog. 
Unlike the other facilities, we don't use a fallback for AUTHPRIV if it
doesn't exist.  Because it is intended for logging sensitive log messages, it
is better that a program trying to log such messages fail than that it log
them insecurely.

Initial patch by Federico Reghenzani.

ad95c2d25c time.time() now uses clock_gettime(CLOCK_REALTIME) if available 
clock_gettime(CLOCK_REALTIME) has a better resolution than gettimeofday().
time.time() falls back on gettimeofday() (and then on other functions) on
error.

fe17b2bc77 Raise MemoryError instead of InvalidOperation/MallocError for compatibility 
with decimal.py. The standard specifies InsufficientStorage (MallocError) as
a sub-condition of InvalidOperation. This allows a calculation to continue
with NaN results when allocation fails.
