Implement the resizing of the file with SetInfo().
Implement the renaming of a file with SetInfo().
Allow to seek past the end of a file.
The support of file resizing implies a rework of the read, write
and close functions. So does the support of seeking past the end
of a file. That why those two changes are done in the same patch.

Fix return codes in case of errors.
Fix translation from EFI open mode to semi-hosting open mode to avoid the
truncate to zero length of an already existing file opened in read/write
or read/write/create mode.

Change mnemonic SEMIHOST_FILE_MODE_CREATE with mnemonic SEMIHOST_FILE_MODE_UPDATE.
The bit referred to by this mnemonic is for the semi-hosting open mode code the
equivalent of the + in the ISO C fopen mode terminology. This allows to select the
so called update mode for which both read and write are allowed on the open file.
The mnemonic SEMIHOST_FILE_MODE_UPDATE is more in line with the ISO C fopen mode
terminology. A description of the ISO C fopen modes can be found here :

Add '.' to the list of directories recognised as the root directory
of semi-hosting.
This is important for EdkShell because listing files in the root directory
of semi-hosting (e.g. ls fsnt0:) is tranformed in a way that uses '.'
Without this patch this results in EdkShell hanging and returning
an "Out of resources" error in the end. With this patch the command
is immediately recognised as unsupported.

ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers.
EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell.
BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine).
