c751993c90 loop: don't override external signal handlers 
qb_loop_signal_add() used to set any signals it wasn't managing
back to SIG_DFL. This is unfriendly behaviour in a library.

002f009941 Remove timerfd usage and go back to timelist. 
timefd is using too much cpu and it is using up
file descriptors.

timelist is also more portable and now I have less
code to maintain.

d823a480dc Fix a compile warning on sparc (epoll_create1) 
The problem is that sys/epoll.h was broken on sparc and alpha for a
bunch of glibc releases.

glibc has the symbol correctly exported, that's why ./configure finds
it, but the header is not always correct. Recent versions of glibc have
the correct header, so we simply workaround the broken ones.

This fix is only necessary to build with --enable-fatal-warnings,
otherwise you simply see a build warning, but there are no runtime
issues at any stage.

8431910be0 LOOP: change timer handle from pointer to index + check. 
This changes the timer hande from a live pointer to a handle
more like hdb handles (minus the ref counting).

What i like about this is it is not neccessary to clear
the applications handle using memset().
