Fix issue 5576 (regex matching bug in expr)
...
Issue 5576 reported a bug in expr, found by the fuzzer. The problem
turns out to be with the regex match operator `:`, which is defined in
POSIX and the GNU manual to match the pattern only when it occurs at
the beginning of the string, i.e., the regex has an implicit `^`
prepended to it. We hadn't been doing that.

* expr: support arbitrary precision integers
Instead of i64s we now use BigInts for integer operations. This means
that no result or input can be out of range.
The representation of integer flags was changed from i64 to u8 to make
their intention clearer.
* expr: allow big numbers as arguments as well
Also adds some tests
* expr: use num-traits to check bigints for 0 and 1
* expr: remove obsolete refs
match ergonomics made these avoidable.
* formatting

Instead of returning an Err it should return the "null string"
(in our case that's the empty string) when the offset or length
is invalid.
