* The following function from <unicode/normlzr.h> is used:
     normalize()

* Until ICU 59, <unicode/normlzr.h> is indirectly included, but this changed with the 59 release. Adding this header has been the right thing to do for many years, so it is backwards compatible and fix compilation with recent ICU.

When upgrading OpenSSL, Step 6 in upgrading guide explains the steps
that need to be taken if asm files need updating. This might not
always be the case and something that needs to be checked from
release to release.

This commit adds an example of using github to manually compare two tags
to see if any changes were made to asm files.

In openssl s_client on Windows, RAND_screen() is invoked to initialize
random state but it takes several seconds in each connection.
This added -no_rand_screen to openssl s_client on Windows to skip
RAND_screen() and gets a better performance in the unit test of
test-tls-server-verify.
Do not enable this except to use in the unit test.
