3ab3e3db6e Mark ARM assembly globals hidden uniformly in arm-xlate.pl.
We'd manually marked some of them hidden, but missed some. Do it in the perlasm
driver instead since we will never expose an asm symbol directly. This reduces
some of our divergence from upstream on these files (and indeed we'd
accidentally lose some .hiddens at one point).

2ab24a2d40 Put arm/aarch64 assembly functions in their own section.
This change causes each global arm or aarch64 asm function to be put
into its own section by default. This matches the behaviour of the
-ffunction-sections option to GCC and allows the --gc-sections option to
the linker to discard unused asm functions on a function-by-function
basis.

Sometimes several asm functions will share the same data an, in that
situation, the data is put into the section of one of the functions and
the section of the other function is merged with the added
“.global_with_section” directive.

c8e664b70a Fix several minor points noticed by Kenny.
∙ Some comments had the wrong function name at the beginning.
  ∙ Some ARM asm ended up with two #if defined(__arm__) lines – one from
    the .pl file and one inserted by the translation script.

73415b6aa0 Move arm_arch.h and fix up lots of include paths.
arm_arch.h is included from ARM asm files, but lives in crypto/, not
openssl/include/. Since the asm files are often built from a different
location than their position in the source tree, relative include paths
are unlikely to work so, rather than having crypto/ be a de-facto,
second global include path, this change moves arm_arch.h to
include/openssl/.

It also removes entries from many include paths because they should be
needed as relative includes are always based on the locations of the
source file.

96ac819197 Remove inconsistency in ARM support.
This facilitates "universal" builds, ones that target multiple
architectures, e.g. ARMv5 through ARMv7.

(Imported from upstream's c1669e1c205dc8e695fb0c10a655f434e758b9f7)

This is a change from a while ago which was a source of divergence between our
perlasm and upstream's. This change in upstream came with the following comment
in Configure:

 Note that -march is not among compiler options in below linux-armv4
 target line. Not specifying one is intentional to give you choice to:

 a) rely on your compiler default by not specifying one;
 b) specify your target platform explicitly for optimal performance,
    e.g. -march=armv6 or -march=armv7-a;
 c) build "universal" binary that targets *range* of platforms by
    specifying minimum and maximum supported architecture;

 As for c) option. It actually makes no sense to specify maximum to be
 less than ARMv7, because it's the least requirement for run-time
 switch between platform-specific code paths. And without run-time
 switch performance would be equivalent to one for minimum. Secondly,
 there are some natural limitations that you'd have to accept and
 respect. Most notably you can *not* build "universal" binary for
 big-endian platform. This is because ARMv7 processor always picks
 instructions in little-endian order. Another similar limitation is
 that -mthumb can't "cross" -march=armv6t2 boundary, because that's
 where it became Thumb-2. Well, this limitation is a bit artificial,
 because it's not really impossible, but it's deemed too tricky to
 support. And of course you have to be sure that your binutils are
 actually up to the task of handling maximum target platform.

eb7d2ed1fe Add visibility rules.
This change marks public symbols as dynamically exported. This means
that it becomes viable to build a shared library of libcrypto and libssl
with -fvisibility=hidden.

On Windows, one not only needs to mark functions for export in a
component, but also for import when using them from a different
component. Because of this we have to build with
|BORINGSSL_IMPLEMENTATION| defined when building the code. Other
components, when including our headers, won't have that defined and then
the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines
in base.h

In the asm code, symbols are now hidden by default and those that need
to be exported are wrapped by a C function.

In order to support Chromium, a couple of libssl functions were moved to
ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.
