Renamed/reverted file->buffer -> file->cache

Browse Source 
And the related config options:

- cfg->file_buffer_size -> cfg->file_cache_size
- file->cfg->buffer_size -> file->cfg->cache_size
- file->cfg->buffer -> file->cfg->cache_buffer

The original motivation to rename this to file->buffer was to better
align with what other filesystems call this, but I think this is a case
where internal consistency is more important than external consistency.

file->cache better matches lfs->pcache and lfs->rcache, and makes it
easier to read code involving both file->cache and other user-provided
buffers.

Keeping the upstream name also helps with continuity.
