Add ARM SHA1 asm implementation from Cryptogams (GH #837, PR #838) Add ARM SHA1 asm implementation from Cryptogams. Cryptogams is Andy Polyakov's project used to create high speed crypto algorithms and share them with other developers. Cryptogams has a dual license. First is the OpenSSL license because Andy contributes to OpenSSL. Second is a BSD license for those who want a more permissive license. Andy's implementation runs about 30% faster than C/C++ code. Testing on a 1 GHz Cortex-A7 shows Cryptograms at 16 cpb, and C++ at 23 cpb. The integration instructions are documented at [Cryptogams SHA](https://wiki.openssl.org/index.php/Cryptogams_SHA) on the OpenSSL wiki.

Use CRYPTOGAMS_armcap_P for ARM (GH #846) Andy advised against removing the global caps variable. This commit reintroduces CRYPTOGAMS_armcap_P. However, due to the shared object symbol loading problem, we needed to use CRYPTOGAMS_armcap_P as a global, and not CRYPTOGAMS_armcap as a local. Using CRYPTOGAMS_armcap_P directly caused the symbol to be marked as R_ARM_ABS32 which avoids the problem with R_ARM_REL32.
