openssl: add configuration options, disable ssl3

Adds the following configuration options:
* using optimized assembler code (was always on before)
* use of x86 SSE2 instructions
* dyanic engine support
* include error messages
* Camellia, Gost, Idea, MDC2, Seed & Whirlpool algorithms
* RFC3779, CMS protocols
* VIA padlock hardware acceleration engine

Installs openssl.cnf with the library as it is used by engines
independent of the openssl util.

Fixes DTLS option that was innefective before.

Disables insecure SSL3 protocol and SHA0.

Adds openwrt-specific targets to Configure script, including asm support
for i386, ppc and mips64.

Strips building dirs from CFLAGS shown in binary.

Skips the fuzz directory during build.

Removed include/crypto/devcrypto.h that was included here, to use the
cryptodev-linux package, now that it was been moved from the packages
feed to the main openwrt repository.

This decreses the size of the ipk binray on MIPS32 by about 3.3%:
