copyright: update all copyright lines and remove year ranges

- they are mostly pointless in all major jurisdictions
- many big corporations and projects already don't use them
- saves us from pointless churn
- git keeps history for us
- the year range is kept in COPYING

checksrc is updated to allow non-year using copyright statements

multi: use larger dns hash table for multi interface

Have curl_multi_init() use a much larger DNS hash table than used for
the easy interface to scale and perform better when used with _many_
host names.

curl_share_init() sets an in-between size.

code style: use spaces around pluses

unit1305: fix compiler warning

calloc and ai_addrlen expect different (usually unsigned) types.

checksrc: warn for assignments within if() expressions

... they're already frowned upon in our source code style guide, this
now enforces the rule harder.

checksrc: stricter no-space-before-paren enforcement

In order to make the code style more uniform everywhere

internals: rename the SessionHandle struct to Curl_easy

code: style updates

unit: make unit test source code checksrc compliant

URLs: change all http:// URLs to https://

unit1603: Added unit tests for hash functions

hostip: fix unintended destruction of hash table

.. and added unit1602 for hash.c

fix refreshing of obsolete dns cache entries

- cache entries must be also refreshed when they are in use
- have the cache count as inuse reference too, freeing timestamp == 0 special
value
- use timestamp == 0 for CURLOPT_RESOLVE entries which don't get refreshed
- remove CURLOPT_RESOLVE special inuse reference (timestamp == 0 will prevent refresh)
- fix Curl_hostcache_clean - CURLOPT_RESOLVE entries don't have a special
reference anymore, and it would also release non CURLOPT_RESOLVE references
- fix locking in Curl_hostcache_clean
- fix unit1305.c: hash now keeps a reference, need to set inuse = 1

Bug #149: Deletion of unnecessary checks before calls of the function "free"

The function "free" is documented in the way that no action shall occur for
a passed null pointer. It is therefore not needed that a function caller
repeats a corresponding check.

This issue was fixed by using the software Coccinelle 1.0.0-rc24.
