9172c9b3dd crypt: reduce allocations 
This changes crypt's use of sync.Pool: Instead of storing slices
it now stores pointers pointers fixed sized arrays.

This issue was reported by staticcheck:

SA6002 - Storing non-pointer values in sync.Pool allocates memory

A sync.Pool is used to avoid unnecessary allocations and reduce
the amount of work the garbage collector has to do.

When passing a value that is not a pointer to a function that accepts
an interface, the value needs to be placed on the heap, which means
an additional allocation. Slices are a common thing to put in sync.Pools,
and they're structs with 3 fields (length, capacity, and a pointer to
an array). In order to avoid the extra allocation, one should store
a pointer to the slice instead.

d5afcf9e34 crypt: try not to return "unexpected EOF" error 
Before this change the code wasn't taking into account the error
io.ErrUnexpectedEOF that io.ReadFull can return properly. Sometimes
that error was being returned instead of a more specific and useful
error.

To fix this, io.ReadFull was replaced with the simpler
readers.ReadFill which is much easier to use correctly.

e43b5ce5e5 Remove github.com/pkg/errors and replace with std library version 
This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.

This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.

3fe2aaf96c crypt: support timestamped filenames from --b2-versions 
With the file version format standardized in lib/version, `crypt` can
now treat the version strings separately from the encrypted/decrypted
file names. This allows --b2-versions to work with `crypt`.

Fixes #1627

1648c1a0f3 crypt: calculate hashes for uploads from local disk 
Before this change crypt would not calculate hashes for files it was
uploading. This is because, in the general case, they have to be
downloaded, encrypted and hashed which is too resource intensive.

However this causes backends which need the hash first before
uploading (eg s3/b2 when uploading chunked files) not to have a hash
of the file. This causes cryptcheck to complain about missing hashes
on large files uploaded via s3/b2.

This change calculates hashes for the upload if the upload is coming
from a local filesystem. It does this by encrypting and hashing the
local file re-using the code used by cryptcheck. For a local disk this
is not a lot more intensive than calculating the hash.

See: https://forum.rclone.org/t/strange-output-for-cryptcheck/15437

f78cd1e043 Add context propagation to rclone 
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions

Context propagation is needed for stopping transfers and passing other
request-scoped values.

d0d6b83a7a fs/accounting: rework to enable accounting to work with crypt and b2 
This removes the old system of part accounting and replaces it with a
system of popping off the accounting reader and wrapping up new ones
as necessary.

This makes it much easier to carry the context down the chain of
wrapped readers and get the limiting as near as possible to the
output.  This makes the accounting more accurate and the bandwidth
limiting smoother.

Fixes #2029 and Fixes #1443
