* Allow access to a struct's underlying memory with `struct[offset, length]`.
* Make accessing a struct's underlying memory more convenient.
* refactor memory access unit tests for improved clarity
https://github.com/ruby/fiddle/commit/c082c81bb5
The same as https://github.com/ruby/ruby/pull/2686, but for musl libc.
Musl is not named as libc.so.6 so the `ldd` hack implemented some lines
below does not work.
This issue happened when `libc.so` and `libm.so` path were not found
and `ldd ruby` command also failed to print the shared dependencies
in `test/fiddle/helper.rb`.
See https://travis-ci.org/ruby/ruby/jobs/611483288#L3018

* Set libc6:armhf as a installing dependency explicitly.
* Remove arm32 from allow_failures.
This removes the related tests, and puts the related specs behind
version guards. This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
* Fix a failing test
This commit fixes the following failure:
```
1) Failure:
Fiddle::TestImport#test_no_message_with_debug [/Users/mrkn/src/github.com/ruby/fiddle/test/fiddle/test_import.rb:152]:
1. [2/2] Assertion for "stderr"

```
* Stop using Bundler.with_clean_env
* Clear existing Ruby environment variables on test_no_message_with_debug
https://github.com/ruby/fiddle/commit/13133ddec8
Calling some syscall functions such as Dir.chroot causes SIGSYS instead
of EPERM on Android.
This change skips all tests that stops the test-suite run.
On osx build https://travis-ci.org/ruby/ruby/jobs/454309945,
```
1) Failure:

slept amount of time.
Expected |200 - 322| (122) to be <= 100.
```
but it succeeds on my macOS machine as is. So it seems that the boundary is
just too strict and prone to random failure by overload.
To make osx Travis build usable, let me loosen the delta requirement.

According to some runs in mjit-test (make test-all RUN_OPTS="--jit-wait"),
this test might not be the cause of its failure.
So, let me try running this again.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64426 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
that times out with test-all w/ --jit-wait.
I'm running the following command on Wecker CI everyday:
```
make test-all TESTOPTS="--color=never --job-status=normal" RUN_OPTS="--disable-gems --jit-wait --jit-warnings" RUBY_FORCE_TEST_JIT=1
```
By running yesterday's all commits, r64354 ran successfully but r64355
didn't. So the test should be fixed to run with --jit-wait at first.

EINTR seems unavoidable in real programs (or MJIT), so maybe
it's not worth dealing with. r64353 relies on POSIX timers
to signal.
Switching pipes and sockets to non-blocking by default would let
us get rid of POSIX timers, timer pthread and this hack:

* vm_core.h (rb_vm_t): move `rb_execution_context_t::safe_level` to
`rb_vm_t::safe_level_` because `$SAFE` is a process (VM) global state.
* vm_core.h (rb_proc_t): remove `rb_proc_t::safe_level` because `Proc`
objects don't need to keep `$SAFE` at the creation.
Also make `is_from_method` and `is_lambda` as 1 bit fields.
* cont.c (cont_restore_thread): no need to keep `$SAFE` for Continuation.
* eval.c (ruby_cleanup): use `rb_set_safe_level_force()` instead of access
`vm->safe_level_` directly.
* eval_jump.c: End procs `END{}` doesn't keep `$SAFE`.
* proc.c (proc_dup): removed and introduce `rb_proc_dup` in vm.c.
* safe.c (rb_set_safe_level): don't check `$SAFE` 1 -> 0 changes.
* safe.c (safe_setter): use `rb_set_safe_level()`.
* thread.c (rb_thread_safe_level): `Thread#safe_level` returns `$SAFE`.
It should be obsolete.
* transcode.c (load_transcoder_entry): `rb_safe_level()` only returns
0 or 1 so that this check is not needed.
* vm.c (vm_proc_create_from_captured): don't need to keep `$SAFE` for Proc.
* vm.c (rb_proc_create): renamed to `proc_create`.
* vm.c (rb_proc_dup): moved from proc.c.
* vm.c (vm_invoke_proc): do not need to set and restore `$SAFE`
for `Proc#call`.
* vm_eval.c (rb_eval_cmd): rename a local variable to represent clearer
meaning.
* lib/drb/drb.rb: restore `$SAFE`.
* lib/erb.rb: restore `$SAFE`, too.
* test/lib/leakchecker.rb: check `$SAFE == 0` at the end of tests.

by `strcpy` ("000" -> "123"). However, the string literal "000" with
`frozen_string_literal: true` returns a string object from frozen
string pool. So that after this test "000" from fstring pool becomes
"123" (modified string). 'test/date/' uses "000" (as fstring) and tests
are fails (we could check with `make test-all TESTS='fiddle date'`).

RUBY_PLATFORM is "x86_64-linux" on a 32-bit (x86) Ruby built and
running on a 64-bit Linux kernel. I also have a /lib64
directory nowadays because I just installed multi-arch support
in userspace. So, fall back to loading based in the size of a
packed "unsigned long" type instead of special-casing.
Tested with both x86 and x86_64 userspace on 64-bit Linux kernel,
as well as x86 with a 32-bit Linux kernel.

Some external functions I wish to call may take a long time
and unnecessarily block other threads. This may lead to performance
regressions for fast functions as releasing/acquiring the GVL is not
cheap, but can improve performance for long-running functions
in multi-threaded applications.
This also means we must reacquire the GVL when calling Ruby-defined
callbacks for Fiddle::Closure, meaning we must detect whether the
current thread has the GVL by exporting ruby_thread_has_gvl_p
in internal.h
* ext/fiddle/function.c (struct nogvl_ffi_call_args):
new struct for GVL release
(nogvl_ffi_call): new function
(function_call): adjust for GVL release
[ruby-core:71642] [Feature #11607]
* ext/fiddle/closure.c (struct callback_args):
new struct for GVL acquire
(with_gvl_callback): adjusted original callback function
(callback): wrapper for conditional GVL acquire
* ext/fiddle/depend: add dependencies
* ext/fiddle/extconf.rb: include top_srcdir for internal.h
* internal.h (ruby_thread_has_gvl_p): expose for fiddle
* vm_core.h (ruby_thread_has_gvl_p): moved to internal.h
* test/fiddle/test_function.rb (test_nogvl_poll): new test
