env exists is a way to test (in hush) if an environment variable
exists.  A workaround existed using printenv but this new command
doesn't require all the stdout/stderr redirection to prevent
printing information to the screen.

Example:
$ set testexists 1
$ env exists testexists && echo "yes"
yes
$ env exists testexists || echo "no"
$ set testexists
$ env exists testexists && echo "yes"
$ env exists testexists || echo "no"
no

We expect boards_by_* function to return the 7th filed, 'Target',
not the 6th field, 'Board name'.

So the function names, boards_by_* are a little misleading,
and should be renamed to targets_by_*.

Commit 27af930e changed the boards.cfg format
and it changed boards_by_field() function incorrectly.
For tegra cpus it returned Board Name field,
not Target field.

This commit restores the behavior prior to 27af930e in the right way.

pxelinux and syslinux differ in their handling of absolute paths in menu
files. A pxelinux path is aways prepended with the bootfile path while
syslinux allows for absolute paths. u-boot was always treating a leading
/ as an absolute path breaking some pxelinux setups. Fix this by adding
a flag to distinguish pxelinux vs. syslinux behavior.

Many platforms duplicate pretty much the same timer code yet they all have
a 32-bit freerunning counter register. Create a common implementation that
minimally requires 2 or 3 defines to add timer support:

CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter
CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter
CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down

All functions are weak or ifdef'ed so they can still be overriden by any
platform.

The definitions for CONFIG_SYS_PROMPT are varied with little reason other
than to display the board name. Over half the definitions are "==> ", so
make this the default. The rest of the boards remain unchanged to avoid
breaking any external scripts expecting a certain prompt.
