macOS's AvailabilityMacros.h does not contain macros for future
versions. If a version macro is not defined, consider only earlier
versions to be targeted.
Header file include/ruby/internal/abi.h contains RUBY_ABI_VERSION which
is the ABI version. This value should be bumped whenever an ABI
incompatible change is introduced.
When loading dynamic libraries, Ruby will compare its own
`ruby_abi_version` and the `ruby_abi_version` of the loaded library. If
these two values don't match it will raise a `LoadError`. This feature
can also be turned off by setting the environment variable
`RUBY_RUBY_ABI_CHECK=0`.
This feature will prevent cases where previously installed native gems
fail in unexpected ways due to incompatibility of changes in header
files. This will force the developer to recompile their gems to use the
same header files as the built Ruby.
In Ruby, the ABI version is exposed through
`RbConfig::CONFIG["ruby_abi_version"]`.
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
We see several occurrence of "diagnostic push/pop" so why not
make them macros. Tested on GCC8 / Clang 6.
Note that ruby.h is intentionally left untouched because we don't
want to introduce new public macros.

* dln.c (dln_incompatible_library_p): renamed as the error message
with dln prefix, since it is not bound to xmalloc restrictively.

* dln.c (xmalloc_mismatch_p): define only when using dlopen,
otherwise dlsym is not available too, and should be used then.

However dlsym() requires such feature so this function is non-
portable by nature. Cannot but suppress warning.

* addr2line.c (follow_debuglink): insert global_debug_dir by using
memmove instead of copying to temporary buffer.
* dln.c (dln_load): use memcpy with the known length instead of
strcpy.
* gc.c (rb_gc_unprotect_logging): use strdup instead of malloc and
strcpy.

version error message to be shared.

* dln.c (dln_load): raise fatal error on OSX not other extension
libraries to refer different libruby.

* dln.c (dln_load): check if a different libruby is loaded by the
extension library, and then bail out to get rid of very frequent
reported stale bug reports.

* configure.in (RUBY_NACL and others): Supports PNaCl.
* dln.c: replace the old hacky dynamic loading over HTTP with nacl_io.
* file.c: tenatively use access(2) instead of eaccess.
(rb_file_load_ok): weaken with attribute but not by postprocess.
* io.c (socket.h): now NaCl has socket.h
(flock): disable here instead of nacl/ioctl.h
* nacl/GNUmakefile.in (CC, LD, NM, AR, AS, RANLIB, OBJDUMP, OBJCOPY):
respect path to them if they are absolute.
This helps naclports to build ruby in their source tree.
(PROGRAM_NMF, .SUFFIXES): support .pnexe for PNaCl.
(ruby.o, file.o): move the hack to attributes in ruby.c and file.c
* nacl/ioctl.h: removed. move the hack to io.c.
* nacl/nacl-config.rb: support arm, pnacl and others.
* nacl/pepper_main.c: support build in a naclports tree.
* ruby.c (rb_load_file): weaken with attribute but not by postprocess.
The patch is by sbc@google.com and the Native Client Authors.

* configure.in (with-jemalloc): also check for header, for ABIs
which JEMALLOC_MANGLE is needed, i.e., Mach-O and PE-COFF
platforms. [ruby-core:62939] [Feature #9113]
* include/ruby/missing.h: include alternative malloc header to
replace memory management functions.
* dln.c, io.c, parse.y, st.c: undef malloc family before
re-definition to suppress warnings.

non-ascii path on Windows. based on the patch by Bugra Barin
