* Now takes ownership of headers, form data and input data
* Split Set* and Adopt* methods to help with proper use of this (Set
does a copy)
* Write documentation.
* imported asc-num.txt as a reference, was used to generate the asc sense table.
* use the sense asc and key tables to know which action and status codes are
to be applied.
* tested with an hard disk and a dvd reader.
* these tables could be reused by the scsi_periph module.
devfs_io() can't fall back to calling vfs_synchronous_io(), if the
device driver doesn't support handling requests asynchronously. The
presence of the io() hook leads the VFS (do_iterative_fd_io()) to
believe that asynchronous handling is supported and set a
finished-callback on the request which calls the io() hook to start the
next chunk. Thus, instead of iterating through the request in a loop
the iteration happens recursively. For sufficiently fragmented requests
the stack may overflow (ticket #9900).
* Introduce a new vnode operation supports_operation(). It can be called
by the VFS to determine whether a present hook is actually currently
supported for a given vnode.
* devfs: implement the new hook and remove the fallback handling in
devfs_io().
* vfs_request_io.cpp: use the new hook to determine whether the io()
hook is really supported.
...from orientation params. Elaborated type specifiers are not needed
for C++ code and removing them makes doxygen happy. Verified working
on both gcc2h and gcc4h builds.
* Fill out the Input related method descriptions and also some other updates
to method and variable descriptions.
* Document Graphics State Methods and a bunch of Drawing Related Methods
* Add a bunch more drawing method descriptions.
* Fill out the rest of the methods of the BView class.
Make it clear that the values provided by the escapement_delta struct are an
input to App Server which allows the user to specify extra horizontal space around each character and is not an output provided by App Server.
Also, lots of little cleanups: formatting, adding return statements and
return values where they were missing, fix spelling mistakes, add newlines to
separate command blocks, remove trailing whitespace.
