PATCH: Implement time-out for connect() in http_fetcher

[Ryan Doyle <rdoyle@xxxxxxxxxx>]

A timeout setting exists in src/libpcp_http/src/http_fetcher.c. This is a library that the Apache PMDA uses to read the server status page (the source of the apache metrics).

I noticed that this library doesn't honour the timeout value when connect()'ing to a HTTP server. The patch implements a timeout for connect() via select().

See patch provided, otherwise it is in the branch "ryan" at git://github.com/ryandoyle/pcp.git.

Cheers
