f051f62445 change ~ add work-around for crate name collisions 
- imported crate name collisions bypass implemented

## [why]

There may be some core or external crates required/used by this project that collide with
uutil names. For example, the `test` util collides with the rust core crate 'test' which
is used behind the scenes for testing. Without the renaming scheme used here, cryptic and
fatal compiler errors occur when compiling the integration tests.

3877cf4bd3 maint/deps ~ pin unstable 'textwrap' crate (marked for later review) 
## [why]

'textwrap' is currently unstable, with "term_size" being an undocumented, but required,
feature. The feature name has already changed within the repository 'master' branch.
But that branch has never been pushed to a new version.

Pin for now with "!maint" mark and comment.

c457dfbbc4 fix/uutils ~ support function/util (aka, applet) symlink aliasing where possible 
## [why]

`std::env::current_exe()` has platform dependent behavior and will often
return the target binary, not the symlink name, when the binary is executed
via symlink. So, to support symlinking, the first (0th) arg from `std::env::args()`
is used, when possible, with fallback to `std::env::current_ext()` if args are
missing or empty.

bebf36bffb change/uutils ~ allow (almost) any name for the multi-binary container 
- final multi-binary will now function correctly with any binary/executable name
- multi-binary container acts as the specified util IF EITHER ...
  1. the binary/executable name exactly matches the name of an applet/util
  2. the binary/exectuable name matches <PREFIX><UTIL_NAME> pattern
     * where the PREFIX is any string ending in a non-alphanumeric character

36a2948959 factor::miller_rabin: Avoid unecessary exponentiation 
Instead of computing a^r and a^(n-1) = a^(r 2ⁱ) separately,
compute the latter by repeatedly squaring the former.

33.6% performance improvement

6b9585b1dc factor::miller_rabbin: Refactor before extracting dividers 
Replace iterated division with u64::trailing_zeros, hoist the selection of `mul`
out of the loop, another cool 49.5% runtime improvement.

418fd61759 factor::factor: Short-circuit the fallback to Pollard's rho

bc11e57962 factor::factor: Use u64::trailing_zero instead of iterated division 
No significant performance impact (most of the time is spent elsewhere),
but an easy and satisfying fix nevertheless.

a1b2522750 factor: Move each factorisation method to its own module 
Also decoupled the factorisation methods; now factor::factor contains
the logic that chains the different algorithms and aggregates results.

As a side-effect, rho::factor now performs extraneous allocations (as each
recursive step creates a new `Factors` value, which is then aggregated into
the previous one) but there is no significant performance impact.

d9095a2539 factor: Refactor (eheh) around a Factors datatype 
It is clearer to see what is going on, as opposed to passing around an
unmarked `Vec<u64>`, and there is a single place to add invariants checks.

This is also a more compact memory representation: each prime factor is
represented only once, with an additional byte for multiplicity.  The
performance impact is however not significant.
