e0a651945c Copyright consolidation: perl files 
Add copyright to most .pl files
This does NOT cover any .pl file that has other copyright in it.
Most of those are Andy's but some are public domain.
Fix typo's in some existing files.

0a4edb931b Unified - adapt the generation of cpuid, uplink and buildinf to use GENERATE 
This gets rid of the BEGINRAW..ENDRAW sections in crypto/build.info.

This also moves the assembler generating perl scripts to take the
output file name as last command line argument, where necessary.

f642ebc1e2 Undo a90081576c 
Undo unapproved commit that removed DJGPP and WATT32

a90081576c Remove DJGPP (and therefore WATT32) #ifdef's. 
DJGPP is no longer a supported platform.  Remove all #ifdef, etc.,
cases that refer to it.  DJGPP also #define'd WATT32, so that
is now removed as well.

b2dba9bf1f Profiling revealed that OPENSSL_cleanse consumes *more* CPU time than 
sha1_block_data_order when hashing short messages. Move OPENSSL_cleanse
to "cpuid" assembler module and gain 2x.

2b247cf81f OPENSSL_ia32cap final touches. Note that OPENSSL_ia32cap is no longer a 
symbol, but a macro expanded as (*(OPENSSL_ia32cap_loc())). The latter
is the only one to be exported to application.

14e21f863a Add framework for yet another assembler module dubbed "cpuid." Idea 
is to have a placeholder to small routines, which can be written only
in assembler. In IA-32 case this includes processor capability
identification and access to Time-Stamp Counter. As discussed earlier
OPENSSL_ia32cap is introduced to control recently added SSE2 code
pathes (see docs/crypto/OPENSSL_ia32cap.pod). For the moment the
code is operational on ELF platforms only. I haven't checked it yet,
but I have all reasons to believe that Windows build should fail to
link too. I'll be looking into it shortly...
