Currently this is managed by the release script. We should also possibly remove the section for "Push artifacts to Maven Central"

release notes: no

Clang currently displays an error if source files generated with protoc are compiled with -Wcomma. This change fixes this as suggested by the compiler itself.

VLAs complicate static analysis and bloat stack size. Replace VLA allocation
with calls to malloc and free.  This will alos the code to build with -Wvla.

This corresponds to the newest reading of RFC 3629, and results
in the largest possible number of character entities by any
valid parser. This may result in a buffer which is oversized,
but never undersized.

This is after further discussion with acozzette in this PR;

In consuming this useful string utility, it was discovered
that the interpretation of leading byte codes 0xf8-0xff
did not conform to either the RFC 3629 nor ISO/IEC 10646
definitions of utf-8.

The IETF RFC describes only 1-4 byte encodings (a limited
number of 4 byte encodings at that), and plainly states in
section 1. Introduction;
   o  The octet values C0, C1, F5 to FF never appear.

Alternately, the ISO definition "R.2 Specification of UTF-8"
preseented in the original IETF RFC 2279 clearly define the
meaning of leading byte values F5 through FD, and RFC 3629
Section 10. Security paragraph 3 calls out this alternate
reading (alterative to "never appears".) F5-F7 begin an
invalid (in the domain of unicode code points) 4-byte UTF-8
sequence (similar to F0-F4), while F8-FC begin a 5-byte
sequence, FC and FD begin a 6 byte sequence.

The curent code is wrong in that it doesn't treat the codes
F8-FF as invalid 1-byte characters, nor does it treat the
codes F8-FD as the correct number of bytes. No valid parser
will land these lead characters 4 bytes forward. Most will
treat these as the 5 or 6 byte utf-32 character and may then
treat the resulting character as invalid, while some parsers
may reject all leading F5-FF characters as a single byte of
erronious input, followed by each invalid continuation byte.

We propose the conventional reading of F8-FD as 5 and 6 byte
sequences as originally defined, while FE-FF must be read
as single byte invalid code points.

Plugins (and some built-in generators) have `--<lang>_opt` flag that
allows passing parameters one-by-one instead of passing them as
`--<lang>_out=<params>:<out_base>`. This PR changes protoc to
allow using `--<lang>_opt` for all (built-in) generators.
