Since the migration request has been hanged for a while, let's switch it
for now without beauty API URL.
Fixes: #555
(cherry picked from commit 2fccb967c52e9f5373494df2773c684dee5ef973)
MSVC does not support SHARED and STATIC libraries with the same name,
so let's just build SHARED libraries by default instead (yes we can add
prefix but let's stick with this).
The reason for this is that in windows shared libraries requires .lib
file too, but this is not static library it is imported library for
shared (doh...), for more info [1] and [2].

[2]: https://blogs.msdn.microsoft.com/oldnewthing/20091013-00/?p=16403
And when we build both static library can and will override shared
library imported part, let's take a look at event_extra.lib:
- before patch [3]:

Long time ago in [1] cmake build was forced to compile both libraries
(SHARED and STATIC), since this is how our autotools build works.
[1]: 7182c2f561570cd9ceb704623ebe9ae3608c7b43 ("cmake: build SHARED and STATIC libraries (like autoconf does)")
And there is no way to configure this (and indeed you need to do this
for MSVC for example), so let's introduce option for this --
EVENT__LIBRARY_TYPE.
Plus now we have INTERFACE libraries, that we can use internally in
libevent's cmake rules to avoid strict to _shared/_static variant of the
libraries to link with samples/tests (we prefer SHARED over STATIC for
linking).
Also bump minimal cmake required version to 3.1 by the following
reasons:
- 3.1 is required for RPATH configuration under APPLE
- 3.0 is required for add_library(INTERFACE) (did not found it in 2.8.x
documentation)
- remove extra conditions
(anyway 3.1 was release 4 years ago, so I guess that most of the systems
will have it)

* official/pr/671:
Capitalise project names consistently in README.md
Indent configure flag section to make markdown format them as code
Use https for resources that support it
Rewords awkward sentences in README.md
Fix typos in README.md

Because it is mauvais ton to use binaries instead of normal packages
(like apt-get in debian, pacman in arch, and others).
Plus that link was borken and according to [1] OpenSSL do not ship
binaries officially.
And personally I don't think that this is not obvious that you need
openssl libraries to build libevent with it's support, and BTW you need
headers too (of course).

(cherry picked from commit 62866f98a5979e3b9ee8db0287be79749fcf7d6a)
This patchset adds next missing things (in compare to autotools):
- pkgconfig
- event_pthreads/event_openssl
- compile shared/static libraries always
And some fixes, because it will not build after fixing other things:
- export missing symbols for cmake (-fvisibility=hidden)
* cmake-missing-bits:
cmake: support visibility for AppleClang too
cmake: fix export absolute path and relative path and cleanup a bit
cmake: generate and install pkgconfig files
cmake: build SHARED and STATIC libraries (like autoconf does)
cmake: add missing event_openssl/event_pthreads libraries
Export symbols for -fvisibility=hidden (under cmake)

It did not work before correctly anyway, since cmake do not reset cache
entries by default, so that reset to "beta" didn't work.
But I don't think that making this variable cached is useful, so let's
remove this.
