b1ee87f402 std: simplify vec.with_c_str 
This also fixes a bug in `vec.with_c_str_unchecked` where we
were not calling `.to_c_str_unchecked()` for long strings.

2d878033fd std: add micro optimization to vec.with_c_str_unchecked 
before:

test c_str::bench::bench_with_c_str_unchecked_long ... bench: 361 ns/iter (+/- 9)
test c_str::bench::bench_with_c_str_unchecked_medium ... bench: 75 ns/iter (+/- 2)
test c_str::bench::bench_with_c_str_unchecked_short ... bench: 60 ns/iter (+/- 9)

after:

test c_str::bench::bench_with_c_str_unchecked_long ... bench: 362 ns/iter (+/-
test c_str::bench::bench_with_c_str_unchecked_medium ... bench: 30 ns/iter (+/- 7)
test c_str::bench::bench_with_c_str_unchecked_short ... bench: 12 ns/iter (+/- 4)

ca66b81283 std: Remove an unnecessary comment from c_str 
The documentation for `.with_c_str()` already says that the pointer
will be deallocated before returning from the function.

e02d1eb171 std: Micro-optimize vec.with_c_str for short vectors 
This now makes it unsafe to save the pointer returned by .with_c_str
as that pointer now may be pointing at a stack allocated array.

I arbitrarily chose 32 bytes as the length of the stack vector, and
so it might not be the most optimal size.

before:

test c_str::bench::bench_with_c_str_long ... bench: 539 ns/iter (+/- 91)
test c_str::bench::bench_with_c_str_medium ... bench: 97 ns/iter (+/- 2)
test c_str::bench::bench_with_c_str_short ... bench: 70 ns/iter (+/- 5)

after:

test c_str::bench::bench_with_c_str_long ... bench: 542 ns/iter (+/- 13)
test c_str::bench::bench_with_c_str_medium ... bench: 53 ns/iter (+/- 6)
test c_str::bench::bench_with_c_str_short ... bench: 19 ns/iter (+/- 0)

51470f3b97 c_str: Add new method .as_str() -> Option<&str> 
Also rustify .as_bytes(), so it no longer calls libc::strlen() and is
inlineable.

6919cf5fe1 rename std::iterator to std::iter 
The trait will keep the `Iterator` naming, but a more concise module
name makes using the free functions less verbose. The module will define
iterables in addition to iterators, as it deals with iteration in
general.

03ef71e262 Add ToCStr method .with_c_str() 
.with_c_str() is a replacement for the old .as_c_str(), to avoid
unnecessary boilerplate.

Replace all usages of .to_c_str().with_ref() with .with_c_str().

48265b779f Check for interior nulls in .to_c_str() 
Previous dicussions about CString suggested that interior nulls should
throw an error. This was never implemented. Add this now, using a
condition (named null_byte) to allow for recovery.

Add method .to_c_str_unchecked() that skips this check.
