Cache fixes:
*) do not close connection if cache file is too small: replace it with
valid one
*) rename ngx_http_file_cache_manager_sleep() to
ngx_http_file_cache_loader_sleep() and do not use it all in cache manager:
this is a vestige of the times when cache manager loaded cache
*) set correct configuration file values while adding path

Cache loader improvements:
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.

Cache size accounting fix: actual cache size on disk was less than
needed by sum of sizes of files loaded by worker processes themselves
while cache loader was running.
The bug has been introduced in r3900.

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.

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,

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
