[PATCH v2 0/6] Consolidation patches for bz12683

[Adhemerval Zanella]

Changes from previous version:

  - Fix m68k undef of __ASSUME_ACCEPT_SYSCALL

  - Split recv{from} patch to one for remove recvfrom from auto-generation
    list and another to remove recv.

  - Split send{to} patch to one for remove sendto from auto-generation
    list and another to remove send.

  - Fixes some typos.

I also checked the changes on sparc64-linux-gnu and powerpc-linux-gnu
aside from previous ones.

This patchset is the initial one I am proposing for upcoming BZ#12683
(Race conditions in pthread cancellation) [1].  General idea is to remove
all the auto-generation cancellation syscall from syscalls.list for
all architectures to simplifiy bz12683 fix.

These patches consolidates the accept, connect, recv, recvfrom, send,
and sendto Linux implementation on default ones.  I have tested
a full build/run on x86_64, i686, x32, powerpc64le, aarch64, and
armhf and a build/check for all other supported architectures
(with run-built-tests=no).  Besides the already broken hppa
build (due the new pthread condition) I saw no regressions.
