In enc/utf_8.c, change maximum byte length of UTF-8 to 4 bytes (from 6)
to conform to definition of UTF-8. This closes issue #13590.

Revert change to maximum of 4 bytes for UTF-8 characters at r58954 temporarily.

I miscalculated for r58934, since we sleep 100ms, and
the worst possible case is 100 Hz in the kernel meaning
we only have 10ms resolution. So, we need to increase
our CPU percentage to >= 10% for this.
This should be more than enough for our CI machines which
have 300 Hz kernels [ruby-core:81429]:

if getrusage(2) is available, to improve precision of Process.times and
its user like lib/benchmark.rb.
On macOS, since getrusage(2) has better precision than times(3),
they are much improved like:
* Before
Process.times
=> #<struct Process::Tms utime=0.56, stime=0.35, cutime=0.04, cstime=0.03>
puts Benchmark.measure { "a" * 1_000_000_000 }
0.340000 0.310000 0.650000 ( 0.674025)
* After
Process.times
=> #<struct Process::Tms utime=0.561899, stime=0.35076, cutime=0.046483, cstime=0.038929>
puts Benchmark.measure { "a" * 1_000_000_000 }
0.343223 0.310037 0.653260 ( 0.674025)
On Linux, since struct rusage from getrusage(2) is used instead of struct tms
from times(2), they are slightly improved like:
* Before
Process.times
=> #<struct Process::Tms utime=0.43, stime=0.11, cutime=0.0, cstime=0.0>
puts Benchmark.measure { "a" * 1_000_000_000 }
0.120000 0.040000 0.170000 ( 0.171621)
* After
Process.times
=> #<struct Process::Tms utime=0.432, stime=0.116, cutime=0.0, cstime=0.0>
puts Benchmark.measure { "a" * 1_000_000_000 }
0.124000 0.048000 0.172000 ( 0.171621)

When sleeping for the tick rate of 100ms (defined in
thread_pthread.c) as we do in test/ruby/test_io.rb
(test_copy_stream_no_busy_wait), it may not be possible to
measure with <= 10ms resolution on 100HZ systems (CONFIG_HZ in
the Linux kernel). So increase the threshold to 15ms (10ms +
5ms slack for slow systems).

Instead, match the poll() implementation used on Linux for now;
as the Linux poll(2) manpage describes using negative FD to
easily ignore an FD in a larger FD set while (sleeping the given
timeout). I'm not entirely sure if matching poll() behavior
is a good idea for a single FD, but it's better than segfaulting
or NoMemoryError.
* thread.c (init_set_fd): ignore negative FD
* test/-ext-/wait_for_single_fd/test_wait_for_single_fd.rb
(test_wait_for_invalid_fd): check values which may trigger
segfaults or OOM

rational.c (i_gcd): replace GCD algorithm from Euclidean algorithm to Stein
algorithm (https://en.wikipedia.org/wiki/Binary_GCD_algorithm).
Some Time methods will call internal quov() function and it calls
Rational#quo -> f_muldiv() -> i_gcd() in rational.c
And some Rational methods also call i_gcd().
The implementation of Euclidean algorithm spent a long time at modulo
operation (ie "x = y % x;").
The Stein algorithm will replace with shift operation which is faster
than modulo.

changes to exts were not taking effect.
