gitweb: provide a routine to display (sub)sections 

The routine puts the given contento into a DIV element, automatically
adding a header div. The content can be provided as a standard scalar
value (which is used as-is), as a scalar ref (which is HTML-escaped), as
a function reference to be executed, or as a file handle to be dumped.

# Group output by placing it in a DIV element and adding a header.
# Options for start_div() can be provided by passing a hash reference as the
# first parameter to the function.
# Options to git_print_header_div() can be provided by passing an array
# reference. This must follow the options to start_div if they are present.
# The content can be a scalar, which is output as-is, a scalar reference, which
# is output after html escaping, an IO handle passed either as *handle or
# *handle{IO}, or a function reference. In the latter case all following
# parameters will be taken as argument to the content function call.
