Update StaticAnalysisTest to check for missing header files. Fix found incorrect header file paths in the demos and projects.

USB_CONFIG_ATTR_BUSPOWERED constant renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed (thanks to NXP Semiconductors).

Run wspurify script on /trunk/ and /branches/ C source files, to remove any trailing whitespace at the end of each line.

Add missing SVN eol-style property to ensure that source code line endings and converted to the native values on checkout.

Fixed incorrect Dataflash buffer use in the DataflashManager_WriteBlocks_RAM() function of several demos/projects (thanks to Jeremy Willden).

Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Seperate out the device demos and project's configuration descriptor structure definitions to clearly indicate what descriptors belong to which interface.

Add new "checksource" target to the library makefiles, for automated source file existance checking.

Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Renamed all low level Endpoint_Read_*, Endpoint_Write_* and Endpoint_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Renamed all low level Pipe_Read_*, Pipe_Write_* and Pipe_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.
