David Benjamin 29270dea85 Split unlock functions into read/write variants. 
Windows SRWLOCK requires you call different functions here. Split
them up in preparation for switching Windows from CRITICAL_SECTION.

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/nid.h
        perl obj_dat.pl ../../include/openssl/nid.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 nid.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. nid.h is the header which defines macros for all the
built-in OIDs in C.

nid.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.
