[Nut-upsdev] Changes to upscli_connect

[Frédéric Bohé]

Hello,

I am currently working on the nut scanner. For detecting available upsd
on the network, I rely on upscli_connect. The problem with this function
is that it calls a blocking "connect" function. So the nut-scanner is
blocked while waiting for the TCP timeout when trying to connect to an
IP without upsd available . Since this timeout may be rather long (3
minutes on my host), I would like to add a timeout parameter to
upscli_connect.
I propose to add a upscli_tryconnect function accepting a timeout
parameter, which will be the copy of the current upscli_connect + the
management of the timeout. The upscli_connect will be only a wrapper on
top of upscli_tryconnect, calling it without timeout.
Please let me know if this makes sense to you.

See a diff in attachment.

Regards,
Fred
