We used to need a wrapper around the core function dns_resolv() to
implement pxe_dns(), because the former function required its argument
to live in low memory.  This is no longer the case and hasn't been for
a while, so remove this unnecessary level of indirection.

When parsing the modules.alias, we shall report it as broken if we
cannot find any valid line in it.

This patch simply count the number of valid lines and report a missing
modules.alias if no valid lines are found.

Check if the first character matches the character to replace, rather
than skipping it and starting with the second.

If the kernel is relocatable and the protected mode code will not fit
in the initially determined location, that code will be moved to the
next available location. However, beginning with commit 8f470e7b, the
code is moved to the initially determined location instead of the next
available location because prot_mode_base is no longer updated to the
correct location. Since whdr->code32_start is updated, it is pointing
to the wrong execution start location, random code is executed and
the machine is rebooted.

Restore the old behavior by assigning prot_mode_base the value of
base. Tested on a machine that exposed this behavior.
