From the Gif spec:
'The output codes are of variable length, starting at <code size>+1 bits per
code, up to 12 bits per code. This defines a maximum code value of 4095
(0xFFF).'
'Because the LZW compression used for GIF creates a series of variable length
codes, of between 3 and 12 bits each'

This CL fixes a leak that can be caused by a longjmp in ErrorData. The method
is renamed to express the fact that it includes such, and a followup should
remove the jmps altogether.

Before, all pointers were being initialized to 0. After raw pointers were
changed to vectors, data() was used in some cases, but now no longer returns
nullptr when it is supposed to. This CL fixes that.

This CL changes the tag_gif_decompress_struct into CGifDecompressor. It cleans

In a way similar to the existing USE_SYSTEM_LIBJPEG. The default is of
course still the DEPS-based zlib checkout.
Changes in v2:
1) Since Chromium doesn't have //third_party:zlib (AKA a "zlib" target in
//third_party/BUILD.GN) all the targets that depended on //third_party:zlib now
depend on third_party:zlib, which always points to PDFium's
third_party/BUILD.GN. The targets that depended on //third_party:zlib in
third_party/BUILD.GN just depend on :zlib instead.
2) Move the zlib bits out of !build_with_chromium block.

Depending on the code table, it's possible to have the largest PREFLEN
value in the huffman table to be > 32. This will, potentially, cause the
calcuation of ((FIRSTCODE[i - 1] + LENCOUNT[i - 1]) << 1 to overflow the
int value and cause a negative shift.
This Cl checks the shift value and failes the initialization if we would
shift a negative value.

- All callers of CFX_DIBitmap methods use nullptr as the ICC Transform.
- The CFX_ScanlineCompositor is always initialized with a null ICC transform.
Many of its methods call TranslateScanline from the ICC module. This method
casts just uses ((CLcmsCmm*)pTransform)->m_hTransform, and this should not be
done when pTransform is nullptr.

Repeated looping over Realloc() with a linearly increasing buffer
size is going to be O(N^2) which is why it was limited to small
cases. But it's wrong to do it anyways, and it kicks out a
lurking issue in PartitionAlloc as it turns out.
See https://crbug.com/709271, but this doesn't actually fix that
issue, it just avoids it.
