Currently when the BitStream runs out of bits it pretends that it
still has content and will continue to return the last byte over and
over again. This Cl updates the jbig decoder to detect that the bit
stream is complete and returns a decode error.

The methods to read n bits from the huffman stream are not correctly
checking that the bits are available. This means, we'll end up reading
0 bits due to the checks below and pretend like the read worked.
This Cl adds the check that we are not at the end of the bit buffer
before attempting the bit read.

- Flush is needed in ~CFX_FxgeDevice, otherwise it may be called after deleting
the bitmap, when calling the destructor of the skia device driver.
- SkDashPathEffect::Make copies the given intervals instead of owning them, so
free the input to that method.
- If StartDIBits creates a new CFX_ImageRenderer, then the corresponding
CancelDIBits needs to delete the handle.

The crash on the new tab page is triggered by processing a transparency.
This creates a new Skia device in CPDF_RenderStatus::LoadSMask():
// cpdf_renderstatus.cpp # 2557
if (!bitmap_device.Create(width, height, format, nullptr))
which sets the Skia clip stack to empty.
It then calls
RenderObjectList()
RenderSingleObject()
ProcessClipPath()
which resets the clip stack;
// cpdf_renderstatus.cpp # 1882
m_LastClipPath = ClipPath;
m_pDevice->RestoreState(true);
At this point m_LastClipPath contains {m_Ref={m_pObject={m_pObj=empty } } }
The impelemntation in CFX_AggDeviceDriver::RestoreState() is
// fx_agg_driver.cpp # 1283
if (m_StateStack.empty())
return;
This hides unbalanced save/restores, but reworking PDFium to balance is nontrivial.

CloneNonCycle() tries to detect cyclic object references without copying
them. There are two issues:
-- for elements in an array or a dictionary, they should be able to
refer to the same object, which are not cyclic;
-- for cyclic referenced elements in an array or a dictionary, do not
clone the element at all. Having nullptr or <key, nullptr> as an element,
like we did before, might cause crash when the element being accessed.
