c1250b6a49 The cache loader performs two tasks: inserting cache objects in inactivity
list and evaluating total cache size. Reading just directory is enough for
this purpose. Elimination of reading cache files saves at least one disk I/O
operation per file.

Preparation for elimination of reading cache files by cache loader:
removing dependencies on the reading:
*) cache node valid_sec and valid_msec are used only for caching errors;
*) upstream buffer size can be used instead of cache node body_start.

ef1f33b0db Use more precise stat.st_blocks to account cache size on Unix
instead of file length rounded to a file system block size.
There is no similar way on Windows, so rounding to a cache->bsize is kept.

a256afd064 fix race condition if during reconfiguration two cache managers try
to delete old inactive entries: one of them removes a entry just locked by
other manager from the queue and the rbtree as long inactive entry,
causes the latter manager to segfault leaving cache mutex locked,
the bug has been introduced in r3727

406a68003c several changes in cache cleanup handling:
*) now ngx_http_file_cache_cleanup() uses ngx_http_file_cache_free()
*) ngx_http_file_cache_free() interface has been changed to accept r->cache
   ngx_http_file_cache_cleanup() must use r->cache, but not r, because
   there can be several r->cache's during request processing, r->cache may
   be NULL at request finalising, etc.
*) test if updating request does not complete correctly
