The function crc32() is needed by the EFI subsystem at runtime. So it has
to be linked into the runtime section together with all dependencies.
Eliminate empty defines local and ZEXPORT.
Mark variables as static which are not exported.

When crc32 is handled by the hash library, it requires the data to be in
big-endian format, since it reads it byte-wise. Thus at present the 'crc32'
command reports incorrect data. For example, previously we might see:
Peach # crc32 40000000 100
CRC32 for 40000000 ... 400000ff ==> 0d968558
but instead with the hash library we see:
Peach # crc32 40000000 100
CRC32 for 40000000 ... 400000ff ==> 5885960d
Correct this.

Add the CRC32 algorithm to the list of available hashes, and make
the crc32 command use hash_command(). Add a new crc32_wd_buf() to
make this possible, which puts its result in a buffer rather than
returning it as a 32-bit value.
Note: For some boards the hash command is not enabled, neither
are sha1, sha256 or the verify option. In this case the full
hash implementation adds about 500 bytes of overhead. So as a
special case, we use #ifdef to select very simple bahaviour in
that case. The justification for this is that it is currently
a very common case (virtually all boards enable crc32 but only
some enable more advanced features).

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.

The crc table was being built as little endian for big endian
targets. This would cause fw_printenv to always fail with
"Warning: Bad CRC, using default environment" messages.

Ported over the more efficient linux crc32() function.
A quick comparsion on ppc:
After changing the old crc32 to do 4 bytes in the
inner loop to be able to compare with new version one can note:
- old inner loop has 61 insn, new has 19 insn.
- new crc32 does one 32 bit load of data to crc while
the old does four 8 bits loads.
- size is bit bigger for the new crc32:
1392(old) 1416(new) of text. The is because the new version
shares code with crc32_no_comp() instead of duplicating code.
- about 33% faster on ppc:
New > crc 0 0xfffffff -> 39 secs
Old > crc 0 0xfffffff -> 60 secs

Legacy NAND had been scheduled for removal. Any boards that use this
were already not building in the previous release due to an #error.
The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed. There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.

Some systems have zlib.h installed in /usr/include/. This isn't the
desired file for u-boot code - we want the one in include/zlib.h.
This rename will avoid the conflict.

In the current top-of-tree, 1.3.3.-rc2, the optional tool
'tools/env/fw_printenv' fails to compile for two reasons:
1) The header watchdog.h cannot be found.
2) The header zlib.h is picked up from the tool chain rather than the
project causing a prototype conflict for crc32.
This patch addresses both of these issues.

Implement watchodg-aware variants of hash calculation functions:
- crc32_wd()
- md5_wd()
- sha1_csum_wd()
The above functions calculate the hash of the input buffer in chunks,
triggering the watchdog after processing each chunk. The chunk size
is given as a function call parameter.

The envcrc.c does sizeof(unsigned long) when calculating the crc, but
this is done with the build toolchain instead of the target tool
chain, so if the build is a 64bit system but the target is 32bits,
the size will obviously be wrong. This converts all unsigned long
stuff related to crc32 to uint32_t types. Compile tested only: output
of ./tools/envcrc when run on a 32bit build system matches that of a
64bit build system.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)
