Adam Langley 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.

README

OID information is generated via a series of perl scripts. In order, the full
list of commands to run are:

        perl objects.pl objects.txt obj_mac.num ../../include/openssl/obj_mac.h
        perl obj_dat.pl ../../include/openssl/obj_mac.h obj_dat.h
        perl obj_xref.pl obj_mac.num obj_xref.txt > obj_xref.h

objects.txt contains the list of all built-in OIDs. It is processed by
objects.pl to output obj_mac.num and obj_mac.h. obj_mac.num is the list of NID
values for each OID. This is an input/output parameter so NID values are stable
across regenerations. obj_mac.h is the header which defines macros for all the
built-in OIDs in C.

obj_mac.h is read by obj_dat.pl to generate obj_dat.h. obj_dat.h contains the
ASN1_OBJECTs corresponding to built-in OIDs themselves along with lookup tables
for search by short name, OID, etc.

obj_mac.num and obj_xref.txt are read by obj_xref.pl to generate
obj_xref.h. obj_xref.txt links signature OIDs to corresponding public key
algorithms and digests. obj_xref.h contains lookup tables for querying this
information in both directions.
