  tests: Simplify .gitignore

Commit 0bcc8e5b was yet another instance of 'git status' reporting
dirty files after an in-tree build, thanks to the new binary
tests/check-block-qdict.

Instead of piecemeal exemptions of each new binary as they are
added, let's use git's negative globbing feature to exempt ALL
files that have a 'test-' or 'check-' prefix, except for the ones
ending in '.c' or '.sh'.  We still have a couple of generated
files that then need (re-)exclusion, but the overall list is a
LOT shorter, and less prone to needing future edits.

  nbd/server: Reject 0-length block status request

The NBD spec says that behavior is unspecified if the client
requests 0 length for block status; but since the structured
reply is documenting as returning a non-zero length, it's
easier to just diagnose this with an EINVAL error than to
figure out what to return.

correct traces in both -parsed and -skipped cases.

Use NBDExport pointer instead of just export name: there is no need to
store a duplicated name in the struct; moreover, NBDExport will be used
further.

  nbd/server: implement dirty bitmap export

Handle a new NBD meta namespace: "qemu", and corresponding queries:
"qemu:dirty-bitmap:<export bitmap name>".

With the new metadata context negotiated, BLOCK_STATUS query will reply
with dirty-bitmap data, converted to extents. The new public function
nbd_export_bitmap selects which bitmap to export. For now, only one bitmap
may be exported.

  qapi: new qmp command nbd-server-add-bitmap

For now, the actual command ix x-nbd-server-add-bitmap, reflecting
the fact that we are still working on libvirt code that proves the
command works as needed, and also the fact that we may remove
bitmap-export-name (and just require that the exported name be the
bitmap name).
