This commit shortens execute_commands loop over all commands by moving
some parts of the code to extra functions. This will help us in a later
patch to avoid duplicate code when the loop over all commands should be
made atomic or not.
No functional changes intended.

Notes:
v9:
* simplified should_process_cmd to be a one liner
* check_shallow_bugs doesn't check of shallow_update being set, rather
the function is just called if that option is set.
v8: no change
v7:
new in v7 as in v7 I'd split up the previous
[PATCH 4/7] receive-pack.c: receive-pack.c: use a single ref_transaction for atomic pushes
as suggested by Eric.
This is pretty much
> patch 1: Factor out code into helper functions which will be needed by
> the upcoming atomic and non-atomic worker functions. Example helpers:
> 'cmd->error_string' and cmd->skip_update' check; and the
> 'si->shallow_ref[cmd->index]' check and handling.
