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.

This made sense when the cipher might have been standardized as-is, so a
DHE_RSA variant could appease the IETF. Since the standardized variant is going
to have some nonce tweaks anyway, there's no sense in keeping this around. Get
rid of one non-standard cipher suite value early. (Even if they were to be
standardized as-is, it's not clear we should implement new DHE cipher suites at
this point.)

They're not called (new in 1.0.2). We actually may well need to
configure these later to strike ECDSA from the list on Chrome/XP
depending on what TLS 1.3 does, but for now striking it from the cipher
suite list is both necessary and sufficient. I think we're better off
removing these for now and adding new APIs later if we need them.
(This API is weird. You pass in an array of NIDs that must be even
length and alternating between hash and signature NID. We'd also need a
way to query the configured set of sigalgs to filter away. Those used to
exist but were removed in
https://boringssl-review.googlesource.com/#/c/5347/. SSL_get_sigalgs is
an even uglier API and doesn't act on the SSL_CTX.)
And with that, SSL_ctrl and SSL_CTX_ctrl can *finally* be dropped. Don't
leave no-op wrappers; anything calling SSL_ctrl and SSL_CTX_ctrl should
instead switch to the wrapper macros.

This guarantees that we never read beyond the first record, even if the
first record is empty. Between removing SSL_set_read_ahead and DTLS
enforcing record boundaries, this means the buffer need never memmove
data.
The memmove isn't really much of a burden and we can probably just put
SSL_set_read_ahead back after the cleanup if desired. But while the
non-existant read_ahead is off, we should avoid reading more than needed.
(Also the current memmove logic is completely wrong for TLS. Checking
align != 0 doesn't make sense. The real reason to memmove is that the
next record may still be full size. So now line 209 of s3_pkt.c should
*actually* be unreachable.)
SSL_R_HTTPS_PROXY_REQUEST detection is now slightly less accurate, but
OpenSSL was already not parsing HTTP completely. We could asynchronously
read the extra 3 bytes once the first 5 match, but that seems
unnecessary. (Shall we just get rid of all these HTTP detectors? The
only consumer of those error codes is some diagnostics logic.)

Rather than sniff for ClientHello, just fall through to standard logic
once weird cases are resolved.
This means that garbage will now read as WRONG_VERSION rather than
UNKNOWN_PROTOCOL, but the rules here were slightly odd anyway. This also
means we'll now accept empty records before the ClientHello (up to the
empty record limit), and process records of the wrong type with the
usual codepath during the handshake.
This shouldn't be any more risk as it just makes the ClientHello more
consistent with the rest of the protocol. A TLS implementation that
doesn't parse V2ClientHello would do the same unless it still
special-cased the first record. All newly-exposed states are reachable
by fragmenting ClientHello by one byte and then sending the record in
question.

BIGNUM itself still uses int everywhere and we may want to audit all the

number of bits fit in an int is sufficient to make everything happy, unless
we're doing interesting arithmetic on the number of bits somewhere.
