Heblikar. Correct a minor 3.x bug in HyperParser discovered by testing.

Claudiu Popa.

The print_diffs() function was not defined, using the assertEqual() is more
reliable.

On Python 3.5, generator now gets their name from the function, no more from
the code. So we get the expected "notmuch" name instead of the generic "coro"

TestCase process to attempt to fix the gentoo buildbot's "Too many
open files" error.

Patch from Nikolaus Rath.

Skipped tests are now marked as skipped, formerly commented-out or
renamed-so-it-doesn't-look-like-a-test tests are uncommented, properly named,
and unconditionally skipped, some tests that simply didn't run before
are now able to run, and a few are split into multiple methods instead of
skipping via 'return' in the middle of a method.  Also, a couple of unused
files are removed completely.

repr(Handle) is shorter for function: "foo" instead of "<function foo at
0x...>". It now also includes the source of the callback, filename and line
number where it was defined, if available.

repr(Task) now also includes the current position in the code, filename and
line number, if available. If the coroutine (generator) is done, the line
number is omitted and "done" is added.
