[PATCH 0/2] Hurd signals: global dispositions and other fixes


I have been working (as a GSoC student for the GNU project) on a series of
patches which improve signal delivery on Hurd. I believe they're ready to
be tested in Debian and therefore I submit the changes I used to build my
own "preview" packages.

Because the series introduces new symbols but we expect them to be used
only by the hurd package, it seems appropriate to add our own deb-symbols
file -- see the first patch thereafter. Somewhat arbitrarily, I used 2.11
as a "baseline" for Hurd's unversionned symbols.

The second patch actually adds the series to debian/patches/hurd-i386.
See bug-hurd [1] and github [2] for the raw material.

Modified eglibc and hurd packages are available in my apt repository [3].
Be aware, though, that the hurd package therein depends on the extra
symbols, and as a consequence your system will break on a libc upgrade if
said libc does not include my patches, or includes them under a different
version ('echo libc0.3 hold | dpkg --set-selections' advised.)
