bitbake: utils: Handle lockfile filenames that are too long for filesystems
The fetcher mirror code can go crazy creating lock filenames which exceed the filesystem limits. When this happens, the code will loop/hang. Handle the filename too long exception correctly but also truncate lockfile lengths to under 256 since the worst case situation is lockfile overlap and lack of parallelism. (Bitbake rev: 63baf3440b16e41ac6601de21ced94a94bdf1509) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
