Add a FX_TryAlloc() for those few cases where we might need to continue
in face of OOM.
Remove FX_AllocNL() (the context of its use would suggest that NL
means "No Limit"). This is used for some big allocations, so replace
it with TryAlloc(). Large allocations may be worth trying to continue
from, since there are few and they have a large chance of failing.

CFX_Object is a type that implements its own new operators that return
NULL on error. There's no need for this given the |new (std::nothrow)|
syntax; in fact, the current code can only work if there is no activity
in the constructors. This may explain the pervasive lack of
constructors and reliance on Init() methods throughout the codebase.
The activity takes place in fx_memory.h, where FX_NEW is mapped onto
the std::nothrow syntax. The rest is just cleanup.
Down the road, we will simply throw and remove all the error-checking
paths for new objects. Landing this patch first will at least show a
simple path back to the old behaviour without having to re-introduce
CFX_Object should someone want to do so in their own fork.

Needed to fix the failed pdfium_unittests on windows. Ironically,
I created these constants so I wouldn't mix up size_t's and off_t's
in these tests, but I didn't apply them consistently.

Follow on to https://codereview.chromium.org/990683002/.
This more closely mimics what fseek() actually does, so as
to avoid subtle bugs down the road.
Move the DecodeData struct into a header so the test can
use it, and provide a constructor for it.
Along the way, I added include guards, removed the p_
prefix from some non-pointer vars, fixed some IWYU, and
resolved some signed/unsigned comparison warnings with
careful casting.

In the process of opj_end_decompress, it will return fail when the end of coding stream is reached. However it returns true in the same scenario implemented in openJPEG. So the final solution is from openJPEG. Return true when the end of coding stream is reached.

I thought I had done this already, apart from the third-party
libraries, but there were a couple remaining (the third-party
libraries will still call this, they should be tweaked
upstream as needed).

This is done by explicitly adding a virtual dtor to interface classes,
since the cost is small given that there are already virtual functions.
The exceptions are for classes that have a Release() or Delete() method,
in which case it is non-virtual and protected to indicate that the virtual
class is never the deletion point.

This reduces rendering time on my test document by over
10 seconds. It is super common for a JBIG2 dictionary to
span multiple pages, so we don't want to decode the same
dictionary over and over again.

QeTable is a 752 byte array that was defined in a header file. This
caused it to be instantiated by the VC++ compiler 12 times, wasting
8,272 bytes of space in the data segment. Because 'const' implies
'static' this did not cause any duplicate symbol errors.
JSCONST_n*HASH are a set of eight variables that are defined in a header
file. This causes them to be replicated 15 times. The variables
themselves are tiny but they are dynamically initialized and this
dynamic initialization code is replicated 15 times.
When tested on pdfium_test.exe the effect of this change is to:
Reduce the .text (code) segment by 3,616 bytes.
Reduce the .rdata section by 8,656 bytes.
Reduce the total binary file size by 13312 bytes.
These are the worst offenders for pdf.dll as shown in:
https://drive.google.com/open?id=1BvubxoA2SU_2e4T5cq7jHTjc1TlT0qOndpIfX3DMeA8&authuser=0
This will also drastically simplify the list of work to be done
for bug 441899 (getting rid of initializers).

This is code cleanup rather than bug fixing.
The motivation for this was to fix the casts at line 97 of the original file. These are wrong; you cannot correct via casting a function signature mismatch when passing a function as an argument. In theory, there's no reason to believe that the compiler will pass args in the same manner for a function of type (void*, size_t, void*) as for a function of type (void*, size_t, some_struct*). The cast will suppress the compile error, but you can't be assured the call will work as intended. In practice, it does, since the last architecture where a void* had a different representation than a struct* went extinct in the late 80s.
In the functions themselves, note that we currently bail out if srcData->offset >= srcData->src_size, so the expression
bufferLength = (OPJ_SIZE_T)(srcData->src_size - srcData->offset)
will always be > 0. Hence the check
if(bufferLength <= 0)
is pointless, esp. since bufferLength is a signed type and < 0 makes no sense.
The opj_seek_from_memory() has a bool return value, so returning -1 on error doesn't seem reasonable. Change this to TRUE/FALSE, and return false on seek past end.
If we're truly passing readonly data, then perhaps it makes sense to make the write() function always return -1. I didn't do this.
Lastly, I capitalize "DecodeData" so that it looks like a struct, and change its members to be size_t's to avoid casting back and forth.

Since the land of https://pdfium.googlesource.com/pdfium/+/3522876d5291922ddc62bf1b70d02743b0850673, memory is assured to be 16 byte aligned. So no need to do this check.
