d120197676 lib/fs: optimize queries that read recent samples for big number of time series
Use standard copy() func instead of mmap-aware copy func for reading recently touched mmap-ed data.
This improves read performance by up to 4x.

a7797dae09 lib/storage: fix Graphite wildcard matching, which has been broken in v1.36.0
v1.36.0 always returns empty responses for Graphite wildcards like the following

   {__name__=~"foo\\.[^.]*\\.bar\\.baz"}

Temporary workaround for v1.36.0 is to add `[^.]*` to the end of the regexp.

d186472081 lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz
Add index for reverse Graphite-like metric names with dots. Use this index during search for filters
like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case.

This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter,
i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".
