[PATCH v2 0/1] environment: move protect_hfs and protect_ntfs into repo_config_values

[Tian Yuchen <cat@malon.dev>]

Hi everyone,

This series continues the ongoing libification effort by moving the
global filesystem variables, 'protect_hfs' and 'protect_ntfs', into
'struct repo_config_values'.

Place them within the per-repository configuration structure
aligns with our goal of removing global states.

For reviewers familiar with previous libification efforts, Derrick Stolee
attempted to wrap this kind of filesystem-level variable using a
lazy-loaded global accessor get_int_config_global() [1].

However, as Glen Choo pointed out in his review of that series [2],
it is strongly preferred to use plain fields in a repository-scoped
struct over global lazy-loaders, provided those fields are properly
initialized during the setup process.

By moving these variables into repo_config_values and parsing
them eagerly, we successfully tie the filesystem security flags
to the specific repository instance without altering the timing
of configuration warnings or introducing new global states.

Thanks!
