- We factor out the code that does the decoding, deinterlacing and color space
converting into its own function. This prepares auto detection of video frame
properties in a later commit. Auto detection means (for example), that you
don't need to know the size of the decoded video frame -before- intitializing
the video codec as it is the case with the current implementation.
- Use the already existent private member variable fHeader to fill out and
return video frame properties.
- Rename some variables to be more self describing.
- No functional change intended.

- As it is rather hard to find useful documentation, on how to use FFMPEG's API
we cut of some research time by just documenting it at the place where it is
most visible to other FFMPEG plugin developers :)

- This small refactoring is in preparation for implementing decoding of partial
video frame data, where one needs to preserve encoded data between multiple
calls to AVCodecDecoder::_DecodeVideo().
- Note: The names fChunkBuffer and fChunkBufferSize are open for discussion.
I'd rather prefer fEncodedDataChunkBuffer and fEncodedDataChunkBufferSize.
But I'd like to take small refactoring steps, and changing the naming would
also touch the AVCodecDecoder::_DecodeAudio() function. I'd rather focus
on improving the video part for now, leaving the audio part alone.
- No functional change intended.

When using the Show Disks icon option, single window navigaton mode,
and starting navigation by the Disks icon, these bugs would occurs
upon entering child poses :
*) The draggable icon at the top right wouldn't appear
*) The file menu wouldn't update properly (for example, the New folder
menu item won't show)
Based in part on dru_ed's patch.
Accidentally renamed these in the header, rename them back to
match the cpp file. These param names might not be very good but
they match the struct variable names. They are private methods
anyway. No functional change intended in either commit.
Besides that this is a nicer interface, it allows us to get a the HPKG
header as a side effect of initializing the reader, thus preventing
seeking backward in the file. This makes "package recompress - <file>"
work.
* Prefix lock functions with __ to mark them as private. Add
forwarding macros to keep existing code working.
* Avoids symbol name clashes with kernel lock APIs, occuring when
using kernellandemu-lib in userlandfs. Thanks to Ingo for the
suggestion.
Until now we always declared in the HPKG header that the package file is
zlib compressed. For uncompressed files we would just store all
individual chunks uncompressed. Now we handle completely uncompressed
files slightly differently: We don't write the redundant chunk size
table anymore. The size savings are minor, but it makes the uncompressed
format read-streamable which may be handy.
* PackageFileHeap{Reader,Writer} as well as Package{Reader,Writer} and
their implementation and super classes do now internally use a
BPositionIO instead of a FD to access the package file. This provides
more flexibility needed for features to come.
* BPackageReader has already grown a new Init() version with a
BPositionIO* parameter.
Simple BPositionIO implementation using the POSIX API on a FD. In effect
similar to BFile, but more easily ported to kernel and boot loader (and
the FD is reusable).
- Reset tooltip when it's no longer needed (i.e. if the file path changes).
Otherwise, we'd erroneously show the old tooltip if the new path was short
enough to no longer be truncated, as would often happen after locating a
missing source file.
* Add support for hubs in AllocateDevice().
* Prevent page fault in FinishTransfers().
* Set fCapabilityLength
* Correct in BIOS ownership code
* Fix context errors in _InsertEndpointForPipe().
* Update constants according to latest Specification (v1.1)
* Fix SMI code (reference
http://lkml.iu.edu/hypermail/linux/kernel/1204.2/02460.html).
* Fix Memory/Device-Slot leaks.
* Fix area allocation for TRBs.
* Fix for Intel Lynx Point and Panther Point chipsets. Also move init
of xhci before ehci, to switch USB 2.0 ports before the ehci module
discovers them.

* Ingo copied the methods into a shared location, and then obviously
"forgot" to let BFS use them. As a side note for Ingo: the complete
error GCC reported was "std::fssh_size_t" not defined with the macro
wrapper as code location. The actual problem was a "using std::size_t"
in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
used in any file system shell, not just the bfs_shell.
* When restoring shared attributes, don't affect CDDB:lookup status
* Volume renames should not affect CDDB:lookup status, only file renames should
This fixes some of the "cddb_daemon not updating CD info" problems.
