The existing implementation was overly complex and hard to understand,
so this simplifies the logic. As part of this a number of issues, such
as the lack of a failure path, have been resolved.
The spec implies that a picture clause of "" should only accept the
empty string, but existing implementation returns that validation does
exist. This is due to the GetPicture() method returning a string,
instead of a pointer or an Optional, so there is no mechanism to
differentiate between a clause with an empty string and the clause not
being present. This CL maintains the existing behaviour, because there
may be code elsewhere that depends on it.
The existing implementation returns validation not existing if the
node under test is non-interactive. Though this seems intuitively
correct, it is problematic, because this logic isn't just called via
an interaction with the node. The validity check could be initiated
by a call from JS attached to an event or a different node. Thus it is
possible for a node under test to be non-interactive, but the result
of the test is still important. The caller may make the node
interactive if it isn't valid, for example. The spec doesn't state
anything about interactivity controlling if validity checks run. This
CL removes the related logic, since it was causing issues with an
example PDF from the wild.

A RetainPtr is already used inside SharedCopyOnWrite, and the API
that CPDF_ContentMark offers is not intuitive. AddMark() and
RemoveLastMark() currently copy the MarkData.
The new API does not perform these copies, but rather leaves it to
the client code.
This is the first step to make CPDF_ContentMarkItems modifiable. As
long as they are inside a SharedCopyOnWrite, they cannot be changed.

This flag was used for enabling GCOV style coverage data
generation. Our code coverage tools now use the native LLVM tools, so
no longer depend on this flag. Having this flag is confusing and a
source of developer error.

Allow sub-streams created from an IFX_SeekableReadStream to provide
stream data without copying memory.
The data will only reside in the top-level stream.
For example:
For file
http://www.major-landrover.ru/upload/attachments/f/9/f96aab07dab04ae89c8a509ec1ef2b31.pdf
(18 Mb)
The memory usage is reduced by ~13 Mb.

To reduce reconnections, read stream data first, then do all checks.
Thereby the DocumentLoader will continue loading data without
