[PATCH] suggested SIGPIPE handling for libcurl

Hi friends,

In bug #1180 [1], we have a clear case where we get a SIGPIPE and there's
currently no way for libcurl to deal with it nicely. This is because the
actual offending write() (or similar) call is made from within OpenSSL. I
suspect other 3rd party libs we use may be able to do the same thing.

The only work-around we have up until now is to recommend that the libcurl-
using applications themselves ignore SIGPIPE. That's also what the curl tool
does now so that it won't die as easily from this problem.

I've written a small patch that shows my suggested fix. It is two functions
that should be called on libcurl-entry and libcurl-exit for all libcurl
functions that risk causing a SIGPIPE. The functions will switch on sigpipe
ignoring and then switch back the "outside's" situation again on exit.
