"The entries in an IFD must be sorted in ascending order by Tag. Note that this is
not the order in which the fields are described in this document."
This way various dimensions, sample and bit sizes cannot be changed at
arbitrary times which reduces the potential for bugs.
The tag reading code also on various places assumes that numerically previous
tags have already been parsed, so this needs to be enforced one way or another.
If this commit causes problems with real world files which are not easy to fix
then some other form of checks are needed to ensure the various dependencies
in the tag reading are not violated.

(cherry picked from commit 8df6884832)
Until now, we would have only attempted to utilize already decrypted
data if it was enough to fill the size of buffer requested, that could
very well be up to 32 kilobytes.
With keep-alive connections this would just lead to recv blocking
until rw_timeout had been reached, as the connection would not be
officially closed after each transfer. This would also lead to a
loop, as such timed out I/O request would just be attempted again.
By just returning the available decrypted data, keep-alive based
connectivity such as HLS playback is fixed with schannel.
(cherry picked from commit 6f8826e4aa)
The dec_buf seems to be properly managed between read calls,
and we have no logic to decrypt before attempting socket I/O.
Thus - until now - such data would not be decrypted in case of
connections such as HTTP keep-alive, as the recv call would
always get executed first, block until rw_timeout, and then get
retried by retry_transfer_wrapper.
Thus - if data is received - decrypt all of it right away. This way
it is available for the following requests in case they can be
satisfied with it.

(cherry picked from commit 85c00643b7)
ttaenc contained (1 << unary) - 1 as an argument for a function
expecting an unsigned int. unary can be as big as 31 in this case.
The type of the shift and the whole expression is int, because 1 fits
into an integer, so that the behaviour is undefined if unary == 31
as the result of the shift can't be represented in an int §. Subtraction
by 1 (which makes the result of the whole expression representable in
an int) doesn't change that this is undefined (it usually leads to
signed integer overflow which is undefined, too).
The solution is simple: Make 1 unsigned to change the type of the
whole expression to unsigned int (as the function expects anyway).
Fixes ticket #8153.
§: This of course presupposes the common int range of -2^31..2^31-1
