This is useful in a situation where one knows that an hmap_node is in some
hmap, but it's not certain which one, and one needs to know whether it is
in a particular one. This is not a very common case; I don't see any
potential users in the current tree, although an upcoming commit will add
one.

This function offers a way to iterate through an hmap in situations where
it is not safe to retain a node pointer.

Until now, the collection of coverage counters supported by a given OVS
program was not specific to that program. That means that, for example,
even though ovs-dpctl does not have anything to do with mac_learning, it
still has a coverage counter for it. This is confusing, at best.
This commit fixes the problem on some systems, in particular on ones that
use GCC and the GNU linker. It uses the feature of the GNU linker
described in its manual as:
If an orphaned section's name is representable as a C identifier then
the linker will automatically see PROVIDE two symbols: __start_SECNAME
and __end_SECNAME, where SECNAME is the name of the section. These
indicate the start address and end address of the orphaned section
respectively.
Systems that don't support these features retain the earlier behavior.
This commit also fixes the annoyance that files that include coverage
counters must be listed on COVERAGE_FILES in lib/automake.mk.
This commit also fixes the annoyance that modifying any source file that
includes a coverage counter caused all programs that link against
libopenvswitch.a to relink, even programs that the source file was not
linked into. For example, modifying ofproto/ofproto.c (which includes
coverage counters) caused tests/test-aes128 to relink, even though
test-aes128 does not link again ofproto.o.
This prepares for adding a new function that deals with a "struct hmap"
moving, as opposed to a "struct hmap_node".
Since there was only a single call to this in the whole tree, and its
caller didn't have any callers of its own at all, also move this function
from hmap.h to hmap.c.
