04308dcaa1 local: add --local-unicode-normalization (and remove --local-no-unicode-normalization)
macOS stores files in NFD form and transferring them like this to some
systems causes the Korean language to display incorrectly.

This adds the flag --local-unicode-normalization to optionally
normalize the file names to NFC.

This also removes the (long deprecated) --local-no-unicode-normalization flag

6ef7178ee4 local: always use readlink to read symlink size
It was discovered on some Android systems, the stat size of a symlink
is different to the size that readlink returns.

This was giving errors like this

    transport connection broken: http: ContentLength=30 with Body length 28

There are enough exceptions to the size of readlink being different to
the size of stat that this patch now always does readlink to work out
the size of a symlink.

Since symlinks are relatively uncommon this shouldn't affect
performance too much and will mean that the size is always correct.

This deprecates the --local-zero-size-links flag which is now
effectively always enabled.

2d7afe8690 local: Add flag --no-preallocate - #3207
Some virtual filesystems (such as Google Drive File Stream) may
incorrectly set the actual file size equal to the preallocated space,
causing checksum and file size checks to fail.

This flag can be used to disable preallocation for local backends of
this type.

df4e6079f1 local: new flag --local-zero-size-links to fix sync on some virtual filesystems
Assume the Stat size of links is zero (and read them instead)

On some virtual filesystems (such ash LucidLink), reading a link size via a
Stat call always returns 0.
However, on unix it reads as the length of the text in the link. This may
cause errors like this when syncing:

    Failed to copy: corrupted on transfer: sizes differ 0 vs 13

Setting this flag causes rclone to read the link and use that as the size of
the link instead of 0 which in most cases fixes the problem.

Fixes #4950

7428e47ebc local: fix sizes and syncing with --links option on Windows - fixes #4581
Before this change rclone returned the size from the Stat call of the
link. On Windows this reads as 0 always, however on unix it reads as
the length of the text in the link. This caused errors like this when
syncing:

    Failed to copy: corrupted on transfer: sizes differ 0 vs 13

This change causes Windows platforms to read the link and use that as
the size of the link instead of 0 which fixes the problem.

local: Add --local-no-set-modtime option to prevent modtime changes
If this option is enabled, rclone will not set modtime of uploaded files and
the backend will return ModTimeNotSupported as its Precision.

Normally rclone updates modification time of files after they are done
uploading. This can cause permissions issues on Linux platforms when
rclone is copying to a CIFS mount where the user rclone is
running as does not own the file uploaded. If this option is enabled,
rclone will no longer update the modtime after copying a file.

0bcf4769fe local: make --local-no-updated provide a consistent view of the objects
Before this change the --local-no-updated flag would not error if the
files changed in size during the transfer. The file could still be
read beyond the size advertised though which caused problems with
certain backends.

After this change we attempt to provide a consistent view of the file
once it has been opened.

Once the file has had stat() called on it for the first time we

- Only transfer the size that stat gave
- Only checksum the size that stat gave
- Don't update the stat info for the file

This means that files that are extending can be transferred - rclone
will transfer the length it saw the first time it listed the file.

14cab0fff0 local: fix "file not found" errors on post transfer Hash calculation
Before this change the local backend was returning file not found
errors for post transfer hashes for files which were moved. This was
caused by the routine which checks for the object being changed.

After this change we ignore file not found errors while checking to
see if the object has changed. If the hash has to be computed then a
file not found error will be thrown when it is opened, otherwise the
cached hash will be returned.

a492c0fb0e local: speed up multi thread downloads by using sparse files on Windows
Before this change rclone didn't use sparse files on Windows. This

wrote the entire file with zeros first on the first write not at the
start of the file.

This change makes the file be sparse on Windows. Linux/macOS files
were already sparse.

402aaca7fe local: don't calculate any hashes by default #3419
Before this change, if the caller didn't provide a hint, we would
calculate all hashes for reads and writes.

The new whirlpool hash is particularly expensive and that has become noticeable.

Now we don't calculate any hashes on upload or download unless hints are provided.

This means that some operations may run slower and these will need to be discovered!

It does not affect anything calling operations.Copy which already puts
the corrects hints in.

f396550934 backend/local: Avoid polluting page cache when uploading local files to remote backends
This patch makes rclone keep linux page cache usage under control when

FADV_SEQUENTIAL to configure read ahead strategy. While reading
the file it issues FADV_DONTNEED every 128kB to free page cache from
already consumed pages.

8243ff8bc8 accounting: isolate stats to groups
Introduce stats groups that will isolate accounting for logically
different transferring operations. That way multiple accounting
operations can be done in parallel without interfering with each other
stats.

Using groups is optional. There is dedicated global stats that will be
used by default if no group is specified. This is operating mode for CLI
usage which is just fire and forget operation.

For running rclone as rc http server each request will create it's own
group. Also there is an option to specify your own group.

9c6f3ae82c local: log errors when listing instead of returning an error
Before this change, rclone would return an error from the listing if
there was an unreadable directory, or if there was a problem stat-ing
a directory entry.  This was frustrating because the command
completely aborts at that point when there is work it could do.

After this change rclone lists the directories and reports ERRORs for
unreadable directories or problems stat-ing files, but does return an
error from the listing.  It does set the error flag which means the
command will fail (and objects won't be deleted with `rclone sync`).

This brings rclone's behaviour exactly in to line with rsync's
behaviour.  It does as much as possible, but doesn't let the errors
pass silently.

c3af0a1eca local: only calculate the required hashes for big speedup
Before this change we calculated all possible hashes for the file when
the `Hashes` method was called.

After we only calculate the Hash requested.

Almost all uses of `Hash` just need one checksum.  This will slow down
`rclone lsjson` with the `--hash` flag.  Perhaps lsjson should have a
`--hash-type` flag.

However it will speed up sync/copy/move/check/md5sum/sha1sum etc.

Before it took 12.4 seconds to md5sum a 1GB file, after it takes 3.1
seconds which is the same time the md5sum utility takes.

f29c6049fc local: preallocate files on Windows to reduce fragmentation #2469
Before this change on Windows, files copied locally could become
heavily fragmented (300+ fragments for maybe 100 MB), no matter how
much contiguous free space there was (even if it's over 1TiB). This
can needlessly yet severely adversely affect performance on hard
disks.

This changes uses NtSetInformationFile to pre-allocate the space to
avoid this.

It does nothing on other OSes other than Windows.
