Avoid libdl dependencies in bundled libverto

The upstream libverto depends on dynamic loading and in particular on
dladdr(), which is not universal.  To avoid this dependency, stub out
support for module loading (by replacing module.c) and instead
integrate the k5ev module directly into the bundled verto library.

This change removes the need to link, include, and invoke libverto
differently depending on whether we're using the bundled library; we
can always just link with -lverto and call verto_default().

-This directory builds a private libverto module using an embedded
-libev with renamed symbols (so we don't leak libev symbols into the
-namespace on platforms where we can't control the export list).
-
-libev has built-in support for this kind of embedding, so we don't
-have to modify the libev sources.  Following libev's documentation,
-the following files have been copied from the ev sources:
-
-  ev.h
-  ev_vars.h
-  ev_wrap.h
-  ev.c
-  ev_select.c
-  ev_poll.c
-  ev_win32.c
-  Symbols.ev
-
-(Symbols.ev wasn't included in the 4.04 tar file due to an oversight,
-so it is taken from the appropriate tag in libev's source repository.)
-
-To rename the exported symbols, we create rename.h from Symbols.ev.
-We also use Symbols.ev to construct the library export list.
-(Renaming libev's symbols would be unnecessary if libev's embedding
-had support for making its API symbols static, but it currently does
-not.)  The source file verto-k5ev.c wraps ev.c with appropriate
-embedding defines, and then defines the libverto module functions
-using the slightly modified contents of libverto's verto-ev.c.
