Ayush Chandekar 9a49aef8dc environment: remove the global variable 'merge_log_config' ...

The global variable 'merge_log_config', set via the "merge.log" or
"merge.summary" settings, is only used in 'cmd_fmt_merge_msg()' and
'cmd_merge()' to adjust the 'shortlog_len' variable.

Remove 'merge_log_config' globally and localize it in
'cmd_fmt_merge_msg()' and 'cmd_merge()'. Set its value by passing it in
'fmt_merge_msg_config()' by passing its pointer to the function via the
callback parameter.

This change is part of an ongoing effort to eliminate global variables,
improve modularity and help libify the codebase.
