The single byte lookups always rely on `memchr` and
never really use the good and bad shifts arrays.

The idea is to use memchr on the first lookup for
binary:match/2 and also after every match on binary:matches/2.
We only use memchr in case of matches because benchmarks
showed that using memchr even when we had false positives
could negatively affect performance.
This speeds up binary matching and binary splitting by 4x
in some cases and by 70x in other scenarios (when the last
character in the needle does not occur in the subject).
The reason to use memchr is that it is highly specialized
in most modern operating systems, often defaulting to
SIMD operations.
The implementation uses the reduction count to figure out
how many bytes should be read with memchr. We could increase
those numbers but they do not seem to make a large difference.

Do not allocate a new map when the value is the same
|

A lot of erts internal messages used behind APIs to create
non-blocking calls, e.g. port_command, would cause the seq_trace
token to be cleared from the caller when it should not.
This commit fixes that and adds asserts that makes sure
that all messages sent have to correct token set.
Fixes: ERL-602

There is no reason to have a larger buffer than this as
the recvmsg call will never return more data.

Before this change, if a write to the uds failed due to
EMFILE to ETOOMANYREFS the entire vm would crash. This
change makes it so that an SIGCHLD is simulated to that
the error is propagated to the user instead of terminating
the VM.

'can not' should mostly be 'cannot'
|
|
|
|
I did not find any legitimate use of "can not", however skipped
changing e.g RFCs archived in the source tree.
