Get rid of the UQ_OPEN_CLEARSTALL USB quirk, as it has no effect.

Stalls seem to be cleared by default when a pipe is opened.
Add a gitignore.

Don't halt the uplcom(4) bulk OUT endpoint.

Doing so seems to cause problems with my PL2303HX bridge, but I haven't
figured out the right fix yet. For now this seems to work fine.

Add a proper fix for the ENDPOINT_HALT clear issue.

When it's determined that we have a PL-2303HX, just send the
vendor-specific commands immediately rather than setting things up for a
clear_stall callback later on when pipes are started.

Add KDB_UNATTENDED to my kernel conf.
Get rid of the depends_on directive in io.d. See bin/171678.
Don't free buffers injected into some libelf structures.

Solaris' and FreeBSD's libelf differ in that the latter frees the
buffer while the former do not (see elf_close() in the respective
libraries). Thus this change is needed to avoid a double free leading to
the jemalloc assertion failure in bin/167103.
Since we're replacing FreeBSD libelf's buffers, we need to take care of
freeing them.
