[PATCH 0/2] [GSoC] add signalfd fdinfo decoding

[leedagee]

Hi! I wrote this patch as my GSoC MicroProject.

This patch adds decode fd feature for signalfds, reading its fdinfo in
procfs and printing the sigmask with signal name decoded.

I'm not sure if it works on a BIG-endian machine because I've wrote some
endianness dependent code. I currently cannot come up with a more elegant
way to deal with this kind of situation: variable length of hex string to
memory buffer conversion. And the CI on github covers only x86 platforms.
