Add 'nand verify' command
Add the 'nand verify' command to perform a dump and fake-write
simultaneously, checking the read bits against those generated by the
write process. Appropriate user documentation for this command has
been added to the user guide as well.
The algorithm presently makes a relatively naive comparison. Some chips
that use ECC may not verify correctly using this implementation, but the
new documentation provides details about this limitation.

In some cases, the FILEIO_NONE access mode may be useful as a parameter

This patch provides helpers APIs that will eliminate duplicated code in

target: make "examined" flag be per-target
Previously this flag was stored in "target_type", so that for example
if there were two ARM7TDMI targets in a scan chain, both would claim

examine() method called.
Move this state to where it should have been in the first place, and
hide a method that didn't need exposure ... the flag is write-once.
Provide some doxygen. The examine() method is confusing, since it
isn't separating one-time setup from the after-each-reset stuff. And
the ARM7/ARM9 version is, somewhat undesirably, not leaving the debug
state alone after reset ... probably more of an issue for trace setup
