[PATCH v1 0/3] environment: migrate more global variables, pt.2

Hi all,

This series moves:

 - (1/3) minimum_abbrev and default_abbrev 
 - (2/3) pack_size_limit_cfg
 - (3/3) assume_unchanged

into repo_config_values to continue the libification effort. 

Note: in commit 1/3, we need (repo != the_repository) checks in the
getters, because some subsystems where the readers of _abbrev
configurations live forbid the use of 'the_repository' and only accept
'repo' [1]. We have to explicitly intercept those intances that are
not 'the_repository'.

Thanks! yuchen
