Only when we have CONFIG_CMD_UNZIP enabled do we have the 'gzwrite'
command. While this command should be separated from CONFIG_CMD_UNZIP
we should also only include the write portion of the gz code in that
case as well.

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

The console includes a global variable and several functions that are only
used by a small subset of U-Boot files. Before adding more functions, move
the definitions into their own header file.

Initial filesystem images are generally highly compressible.
Add a routine gzwrite that allows gzip-compressed images to be
written to block devices.

The output buffer size must not be reset by the gzip decoder or there
is a risk of overflowing memory during decompression.

This allows us to add a proper zalloc() func (one that does a zeroing
alloc), and removes duplicate prototypes.

As usually done in U-Boot, the watchdog_reset code is called via a
macro (WATCHDOG_RESET). In zlib.c this was done differently, by using
a function pointer which is initialized with WATCHDOG_RESET upon watchdog
usage or with NULL otherwise. This patch now uses the plain
WATCHDOG_RESET macros to call the function resulting in slightly smaller
U-Boot images and simpler code.
U-Boot code size reduction:
PowerPC board with watchdog support (lwmon5):
-> 80 bytes smaller image size
PowerPC board without watchdog support (sequoia):
-> 112 bytes smaller image size

Now that the other architecture-specific lib directories have been
moved out of the top-level directory there's not much reason to have the
'_generic' suffix on the common lib directory.
