MFC r256642:
Since C++ typeinfo objects are currently not guaranteed to be merged at
runtime by the dynamic linker, check for their equality in libcxxrt by
not only comparing the typeinfo's name pointers, but also comparing the
full names, if necessary. (This is similar to what GNU libstdc++ does
in its default configuration.) The 'deep' check can be turned off again
by defining LIBCXXRT_MERGED_TYPEINFO, and recompiling libcxxrt.

MFC r277944:
Partially revert r273382, to reduce diffs against upstream. This was a
temporary fix to solve a conflict with an older version of libc++, and
it is no longer relevant.
MFC r278010:
Revert r256642, not only to reduce diffs against upstream libcxxrt, but
also because it is the wrong approach: comparing typeinfo names deeply
causes trouble if two loaded DSOs use independent types of the same
name.
In addition, this particular change was never merged to FreeBSD 10.x and
9.x, so let's get rid of it before it ends up in an 11.x release.

Add netmap support to libpcap. Tcpdump and other native pcap clients
can now run directly on netmap ports using netmap:foo or valeXX:YY
as device names.
Modifications to existing code are small and trivial,
the netmap-specific code is all in a new file.
Please be aware that in netmap mode the physical interface is
disconnected from the host stack, so libpcap will steal the traffic
not just make a copy.

MFC note:
r276646 ("do not erronously export 'openat' symbol from rtld") is not
applicable to stable/10 yet, since PATHFDS support was not merged.
Since the merge of file 5.21 in r276415 and r276416, stable/9 and
stable/10 cannot be built from FreeBSD 8.x. This is because the
build-tools stage requires libmagic, but lib/libmagic/config.h was
generated on head, and it now enables using the xlocale.h APIs, which
are not supported on 8.x (and on 9.x before __FreeBSD_version 900506).
See also the start of this thread on -stable:
https://lists.freebsd.org/pipermail/freebsd-stable/2015-January/081521.html
To fix this, conditionalize the use of xlocale.h APIs to make
bootstrapping from older FreeBSD versions work correctly.
