s3fs: add option free_space_ratio to control cache size (#2351) 
* Try to cleanup cache directory when initing without enough disk space

Also optimize log messages to print detailed errors to the user.

* s3fs: add option free_space_ratio to control cache size

Since the ensure_diskfree option is not convenient enough, we have added
a new option "-o free_space_ratio" to control the space used by the s3fs
cache based on the current disk size.

The value of this option can be between 0 and 100. It will control the
size of the cache according to this ratio to ensure that the idle ratio
of the disk is greater than this value.

For example, when the value is 10 and the disk space is 50GB, it will
ensure that the disk will reserve at least 50GB * 10% = 5GB of remaining
space.

15b7450713 Convert file offsets from size_t to off_t 
The latter is 64-bits on 32-bit platforms when specifying
-D_FILE_OFFSET_BITS=64.  This allows early Raspberry Pis to use files
larger than 2 GB.  It also cleans up some ugly casting.  Fixes #620.
Fixes #656.

20da0e4dd3 Fix intermittent upload failures on macOS 
There were multiple problems with the FdManager::GetFreeDiskSpace() function
on macOS:
1) When calling statvfs(), f_frsize should be used instead of f_bsize when
converting available blocks to bytes.  This was causing the free space
calculation to be incorrect.
2) On macOS, fsblkcnt_t is a 32-bit integer.  Thus, when calculating available
disk space, there were frequently overflows.  This caused s3fs to incorrectly
determine that the cache location was out of space in the middle of a transfer
which caused uploads to fail.  Changing this to a uint64_t resolves the
problem.
