This series moves 'trust_executable_bit' and 'has_symlinks' into
'struct repo_config_values' to tie them to the specific repository
instance they were read from. Eager parsing is maintained because
these two flags are heavily consulted in hot paths.

Note: 'repo_config_values()' still does not support any struct
repository other than the_repository due to how deeply these flags
are accessed. In other words, this series of patches is laying
the groundwork for the eventual elimination of the_repository.

Previous related work:

[PATCH 2/6] config: add trust_executable_bit to global config [1]
[PATCH] Refactor 'trust_executable_bit' to repository-scoped setting [2]
(This previous attempt was unsuccessful because the target location
selected was 'struct repo_settings', which our analysis indicated
was not the optimal choice. For further details, please see: [3])

[PATCH 5/6] config: move has_symlinks [4]

RFC:

 - Is the locations of the newly introduced definitions/macros
 appropriate?

Change since V5:

 - do not intruduce new global variable to deal with compat/mingw.c.
 Make use of macro preprocessing to allow platforms to override
 platform_has_symlinks().

Thanks!
