graft: don't preserve most extra fields This backs out changeset 804abe8999f3. See the previous patch for why we're doing this.

amend: don't preserve most extra fields This backs out changeset 39163708825cd. There are some extra fields that absolutely should not be preserved, like the convert_revision field introduced by the convert and hgsubversion extensions. The problem with extensions blacklisting certain extra fields is that they might not be enabled at the time the amend is performed. In the long run we probably want separately marked transferable and non-transferable extra fields, but for now restore the old Mercurial 3.6 behavior.

histedit: fix typo in documentation

osutil: do not abort loading pure module just because libc has no recvmsg() On Solaris, recvmsg() is provided by libsocket.so. We could try hard to look for the library which provides 'recvmsg' symbol, but it would make little sense now since recvfds() won't work anyway on Solaris. So this patch just disables _recvmsg() on such platforms. Thanks to FUJIWARA Katsunori for spotting this problem.

osutil: disable compilation of recvfds() on unsupported platforms It appears that Solaris doesn't provide CMSG_LEN(), msg_control, etc. As recvfds() is only necessary for chg, this patch just drops it if CMSG_LEN isn't defined, which is the same workaround as Python 3.x. https://hg.python.org/cpython/rev/c64216addd7f#l7.33
