copyright: fix out-of-date copyright ranges and missing headers

Reported by the new script 'scripts/copyright.pl'. The script has a
regex whitelist for the files that don't need copyright headers.

Removed three (mostly usesless) README files from docs/

-An overview of the six time values available from curl_easy_getinfo()
-
-curl_easy_perform()
-    |
-    |--NT
-    |--|--CT
-    |--|--|--PT

-NT = CURLINFO_NAMELOOKUP_TIME. The time it took from the start until the name
-     resolving was completed.
-CT = CURLINFO_CONNECT_TIME. The time it took from the start until the connect
-     to the remote host (or proxy) was completed.
-PT = CURLINFO_PRETRANSFER_TIME. The time it took from the start until the file
-     transfer is just about to begin. This includes all pre-transfer commands
-     and negotiations that are specific to the particular protocol(s)
-     involved.
-ST = CURLINFO_STARTTRANSFER_TIME. The time it took from the start until the
-     first byte is just about to be transferred.
-TT = CURLINFO_TOTAL_TIME. Time of the previous transfer. This time does not
-     include the connect time (CT), so if you want the complete operation
-     time, you should add that.
-RT = CURLINFO_REDIRECT_TIME. The time it took for all redirection steps
-     include name lookup, connect, pretransfer and transfer before final
-     transaction was started. So, this is zero if no redirection took place.
