Move public headers to include/openssl/ Previously, public headers lived next to the respective code and there were symlinks from include/openssl to them. This doesn't work on Windows. This change moves the headers to live in include/openssl. In cases where some symlinks pointed to the same header, I've added a file that just includes the intended target. These cases are all for backwards-compat.

Various documentation fixes. Add some missing headers and ensure each header has a short description. doc.go gets confused at declarations that break before the first (, so avoid doing that. Also skip a/an/deprecated: in markupFirstWord and process pipe words in the table of contents.

Clean up the DES_key_schedule logic. It's not clear why OpenSSL had a union. The comment says something about sizes of long, since OpenSSL doesn't use stdint.h. But the variable is treated as a bunch of uint32_t's, not DES_cblocks. The key schedule is also always used by iterating or indexing into a uint32_t*, treating the 16 2-word subkeys as a single uint32_t[32]. Instead, index into them properly shush any picky tools. The compiler should be able to figure out what's going on and optimize it appropriately.

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.
