There seems to be tools producing incorrect 'end of bitmap data'
markers '0100' in a RLE bitmap. Drawing such bitmaps can result
in overwriting memory above the frame buffer. E.g. on MPC5121e
based boards this memory can contain U-Boot environment.
We may not rely on the correct end of bitmap data marker 0001
only, but also have to check whether we are going to draw a
valid frame buffer scan line.
The patch provides a fix by maintaining a pixel counter
which is incremented by the amount of pixels we are going
to draw. If the counter exceeds frame buffer pixels limit
we stop the drawing with the error message.

u-boot environments, esp. when boards are shared across multiple
users, can get pretty large and time consuming to visually parse.
The grepenv command this patch adds can be used in lieu of printenv
to facilitate searching. grepenv works like printenv but limits
its output only to environment strings (variable name and value
pairs) that match the user specified substring.
the following examples are on a board with a 5313 byte environment
that spans multiple screen pages:
Example 1: summarize ethernet configuration:
=> grepenv eth TSEC
etact=FM1@DTSEC2
eth=FM1@DTSEC4
ethact=FM1@DTSEC2
eth1addr=00:E0:0C:00:8b:01
eth2addr=00:E0:0C:00:8b:02
eth3addr=00:E0:0C:00:8b:03
eth4addr=00:E0:0C:00:8b:04
eth5addr=00:E0:0C:00:8b:05
eth6addr=00:E0:0C:00:8b:06
eth7addr=00:E0:0C:00:8b:07
eth8addr=00:E0:0C:00:8b:08
eth9addr=00:E0:0C:00:8b:09

Example 2: detect unused env vars:
=> grepenv etact
etact=FM1@DTSEC2
=>
Example 3: reveal hardcoded variables; e.g., for fdtaddr:
=> grepenv fdtaddr
fdtaddr=c00000
nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $fdtaddr

=> grep $fdtaddr
fdtaddr=c00000
my_boot=bootm 0x40000000 0x41000000 0x00c00000
my_dtb=tftp 0x00c00000 $prefix/p4080ds.dtb

This patch also enables the grepenv command by default on
corenet_ds based boards (and repositions the DHCP command
entry to keep the list sorted).

commit 560d424b6d "env: re-add
support for auto-completion" fell short of its description -
the 'used' logic in hmatch_r was reversed - 'used' is 0 if
the hash table entry is not used, or -1 if deleted. This
patch makes hmatch_r actually match on valid ('used') entries,
instead of skipping them and failing to match anything.
typing 'printenv tft' and hitting 'tab' now displays valid
choices for variable names.

This patch fixes problems in the handling of redundant environment in env_sf.c
The major problem are double calls of free() on the allocated buffers,
which damages the internal data of malloc and crashes on next call.
In addition, the selection of the active environment had errors and compiler
warnings, which are corrected by this patch.
