Victor Stinner 8bcf312d09 Issue #27786: Simplify x_sub()

can be used directly to negate the number.

Yury Selivanov 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.

Serhiy Storchaka bb6e4a0b31 Issue #24731: Fixed crash on converting objects with special methods 
__bytes__, __trunc__, and __float__ returning instances of subclasses of
bytes, int, and float to subclasses of bytes, int, and float correspondingly.

Victor Stinner 199c9a6f4b Fix long_format_binary() 
Issue #25399: Fix long_format_binary(), allocate bytes for the bytes writer.

Victor Stinner 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.

Victor Stinner 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.

R David Murray 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.)

Serhiy Storchaka 20b39b27d9 Removed redundant casts to `char *`.

Victor Stinner 12174a5dca Issue #22156: Fix "comparison between signed and unsigned integers" compiler 
warnings in the Objects/ subdirectory.

PyType_FromSpecWithBases() and PyType_FromSpec() now reject explicitly negative
slot identifiers.

Victor Stinner 45e8e2f218 Issue #21490: Add new C macros: Py_ABS() and Py_STRINGIFY() 
Keep _Py_STRINGIZE() in PC/pyconfig.h to not introduce a dependency between
pyconfig.h and pymacros.h.

Tim Peters 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.
