Description

Enhance "lfs find" to add the following mirror related search options:

[!] --mirror-count|-N [+-]<mirror_cnt>

Number of mirrors.

[!] --file-state <file_state>

State of a mirrored file.
A mirrored file can be one of the following states:

RDONLY - the mirrored file is in read only state, all of the mirrors contain the up-to-date data;
WRITE_PENDING - the mirrored file is being written;
SYNC_PENDING - the mirrored file is being resynchronized.

The user-friendly file state names would be "ro", "write" and "sync".
