When I changed the Rust parser to handle 128-bit ints, this
inadvertently broke some other gdb commands. For example, "info
symbol 0xffffffffffffffff" now fails, because the resulting value is
128 bits, but this is rejected by extract_integer.
This patch fixes the problem by changing extract_integer to allow
over-long integers as long as the high bytes are either 0, or (for
signed types) 0xff.
Regression tested on x86-64 Fedora 38.

The contents of these files was copied from defs.h and findvar. Copy

Move the declarations out of defs.h, and the implementations out of
findvar.c.
I opted for a new file, because this functionality of converting
integers to bytes and vice-versa seems a bit to generic to live in
findvar.c.
