absl::FormatTime() and absl::ParseTime() format specifiers:
- %EZ now accepts 'z' in addition to 'Z' as a synonym for +00:00.
- %ET is introduced, producing 'T' on output, and accepting 'T'
  or 't' on input.  This is for the RFC3339 date-time separator.

8049b74349486a0026932b86d29c380b195e1cba by Laramie Leavitt <lar@google.com>:

Remove the MockingBitGenBase base class in favor of type-erasure in BitGenRef.

In Abseil random, mocking was split across two different classes,
MockingBitGenBase and MockingBitGen. This split existed because Google Mock is a
test-only library that we don't link into production, so MockingBitGenBase
provided a low-overhead scaffold used to lookup mocks when in test code, but
which is unused in production code.

That has been replaced by type-erasure which looks for a method named
CallImpl with the correct signature.

Weaken the coupling between MockingBitGen, DistributionCaller, and MockOverloadSet.

Rename CallImpl to InvokeMock()

Previously, the implementation of DistributionCaller was also split across different files using explicit instantiation of the DistributionCaller struct and some details in the Mocking classes. Now Distribution caller uses the presence of the InvokeMock() method to choose whether to use the mockable call path or the default call path.

1741d80e08050e1939605f70ca6ff64809785c85 by Gennadiy Rozental <rogeeff@google.com>:

Introduce public interface to access reflection handle corresponding the flag.

This interface will be the only official way to access flag reflection information from the flag object. The other internal methods will eventually disappear.

PiperOrigin-RevId: 313734006

c375bead457de29d9c29595d16c66d3e5125b585 by Abseil Team <absl-team@google.com>:

Improve documentation of absl::c_partial_sort_copy.

This function takes no middle parameter, instead using the size of the result
container to determine the size of the partial sort.

bbc759d43656b1b996ad558f23c852a9f14129d2 by Gennadiy Rozental <rogeeff@google.com>:
