3e66e73f68 Skip IRELATIVE relocations when loader processes ELF files.
ifuncs can be only called in the (early boot) kernel environment, so
postpone resolving until early stage of the kernel boot.  This commit
is performed in advance to make loaders on most machines updated
before ifuncs appear in the kernels.

7f3384f4af Interact is always called with NULL. Simplify code a little by
removing this argument, and expanding when rc is NULL. This
effectively completes the back out of custom scripts for tftp booted
loaders from r269153 that was started in r292344 with the new path
tricks that obsoleted it.

2976ca2efb Simplify things a little. The RETURN macro isn't required. It's only
used once, inside an #ifdef where it would be defined to be return.

Something subtle is creating problems for disk access on ubldr. Back
it out unti that can be sorted out.

b8955e64b9 Fix regression with lua import
Don't print when we can't find a file. Copy it instead to the error
buffer. Higher level routines determine if it's appropriate to print
the error message.

Also, remove dead code (labeled bogusly lost functionality) since we
never used that functionality. Remove unused arg from interact() too.

a639b14c02 Create interp class.
Create an interp class. Use it to separate out the different types of
interpreters: forth and simple with function pointers rather than
via #ifdefs.

6cbf877860 Prefer stdint.h to inttypes.h since the added prototypes form the
latter aren't used. Prefer sys/link_elf.h to link.h so we're only
dependent on the kernel tree. The default installation of link.h just
includes this file, and any benefit from that is outweighed by the
hassle it causes. This reduces the footprint of files needed from the
system includes (or sysroot in buildworld).

7f37401396 Fix theoretical integer overflow issues. If the product here is
greater than 2^31-1, then the result will be huge. This is unlikely,
as we don't support that many sections, but out of an abundace of
caution cast to size_t so the multiplication won't overflow
mysteriously when size_t is larger than 32-bits. The resulting code
may be a smidge larger, but this isn't super-space critical code.
