8bcf312d09 Issue #27786: Simplify x_sub() 
The z variable is known to be a fresh number which cannot be shared, Py_SIZE()
can be used directly to negate the number.

e0b23095ee Issues #26289 and #26315: Optimize floor/modulo div for single-digit longs 
Microbenchmarks show 2-2.5x improvement.  Built-in 'divmod' function
is now also ~10% faster.

be75b8cf23 Issue #25349: Optimize bytes % int 
Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X.
_PyBytesWriter is now used to format directly the integer into the writer
buffer, instead of using a temporary bytes object.

Formatting is between 30% and 50% faster on a microbenchmark.

5783fd2c58 Issue #24999: In longobject.c, use two shifts instead of ">> 2*PyLong_SHIFT" to 
avoid undefined behaviour when LONG_MAX type is smaller than 60 bits.

This change should fix a warning with the ICC compiler.

861470c836 #16518: Bring error messages in harmony with docs ("bytes-like object") 
Some time ago we changed the docs to consistently use the term 'bytes-like
object' in all the contexts where bytes, bytearray, memoryview, etc are used.
This patch (by Ezio Melotti) completes that work by changing the error
messages that previously reported that certain types did "not support the
buffer interface" to instead say that a bytes-like object is required.  (The
glossary entry for bytes-like object references the discussion of the buffer
protocol in the docs.)

9259c21a63 Issue #19171: speed some cases of 3-argument long pow(). 
Reduce the base by the modulus when the base is larger than
the modulus.  This can unboundedly speed the "startup costs"
of doing modular exponentiation, particularly in cases where
the base is much larger than the modulus.  Original patch
by Armin Rigo, inspired by https://github.com/pyca/ed25519.

Merged from 3.3.

02515f7a3a Minor consistency fixes for some longobject.c exception messages: 
- replace 'long int' / 'long' by 'int'
 - fix capitalization of "Python" in PyLong_AsUnsignedLong
 - "is too large" -> "too large", for consistency with other messages.

 * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure
 * Fix also some calls to PyDict_SetItemString(): handle error
