The out_row_buffer of BMPDecompressor is made a vector. This forces the
class to have constructor/destructor. Some other members were changed
to be of size_t instead of int32_t.

This CL creates BMPDecompressor from a struct and moves into this class
many methods which naturally belong to it.

The path creation method begins with an open MoveTo point. If nothing
else is added, CFX_PathData::GetBoundingBox will try an OOB access in
its m_Points. This CL adds a check similar to the one in
CPDF_StreamContentParser::AddPathObject.

It's possible to create a stream of length 0 in a PDF document.
Currently the code will early exit and return a nullptr. This causes
issues when you want to print the given PDF as the FPDF_ImportPages code
ends up only generating up to the zero length object.
This CL allows creating streams with length 0 and updates the PDF saving
code to output a blank stream.

The pal_num member of bmp_ptr indicates the number of color indices
used by the bitmap. This CL returns an error when an invalid index is
found, since otherwise a heap-buffer-overflow can occur since the size
of m_pSrcPalette is calculated based on pal_num.

This avoids a stale delegate pointer issue in the module. In theory,
it should also allow for multiple decodes at the same time from
different contexts within the same module, but this isn't used.
Rename associated context, and use |new| to create it. Along the
way, resolve a subtle FX_Alloc() vs. user-supplied callback
free() issue, and remove supporting code.
