gitweb: Add optional "time to generate page" info in footer
Add "This page took XXX seconds and Y git commands to generate"
to page footer, if global feature 'timed' is enabled (disabled
by default). Requires Time::HiRes installed for high precision
'wallclock' time.
Note that Time::HiRes is being required unconditionally; this is
because setting $t0 variable needs to be done fairly early to have
running time of the whole script. If Time::HiRes module were required
only if 'timed' feature is enabled, the earliest place where starting
time ($t0) could be calculated would be after reading gitweb config,
making "time to generate page" info inaccurate.
This code is based on example code by Petr 'Pasky' Baudis.
