By default Neovim searched a Luajit instalation and linked against
the luajit library.
In practice Neovim only requires luajit to run the unit tests. All other
targets only require lua and the correct lua modules. This commit:
1. Remove the strict dependency on Luajit
2. Makes the unittest target depend on the lua 'ffi' module.
If the module is not available the target is not enabled
and a message is displayed.
By default, find_library() searches all directories for one possible
name and then looks for the next name. To make sure we're building
against the same headers and libraries, look for all names in a
directory before moving to the next one.
In 33bc332, version constraints were added to pkg_search_module(), but
that only affects the set of directories searched by
find_library()/find_path().
Once the header directory is found, parse the version from
version_master.h so it can be checked by the find_package() call in the
root CMakeLists.txt.
libmsgpack was the old C++ library provided by msgpack-c. The C library
is libmsgpackc.
The C++ support became header-only, but there was a bug
(msgpack/msgpack-c#395) wherein using msgpack-c's CMake build system
would only install libmsgpack instead of libmsgpackc.
Searching for both libraries, but preferring libmsgpackc, allows for
building against older msgpack-c releases and prepares for the upcoming
msgpack-c release which fixes the aforementioned issues.

When building for X86 the CMake check_library_exists always fails to find
functions from the Win32 API due to name mangling conventions. The convention
for API functions is __stdcall and the CMake test code assumes __cdecl. Since
these are libraries from the Windows API we can simply link against the
libraries without checking for the functions.
Before this change, building Neovim would recursively search parent
directories for a .git directory. If Neovim was downloaded as a tarball
(i.e. without a .git directory), but placed in a subdirectory of
a Git repository, this caused a CMake error. Such a situation could
occur when packaging Neovim, for example.
Unfortunately, the previous attempt in #3317 did not fix this problem.
* Split build steps to utilize the Travis build lifecycle.
* Move shell code from `.travis.yml` into Bash files in `.ci/`,
one file for each step of the Travis build lifecycle.
* Use configuration variables in `.travis.yml` to change
build behavior (e.g. build 32-bit with `BUILD_32BIT=ON`).
* Keep all configuration in environment variables in
`.travis.yml`. In scripts, concatenate environment variables
according to configuration to change to different behavior.
* Add GCC 5 builds for Linux.
* Use Travis's caching feature [1] for third-party dependencies
and pip packages.
* Allow failures MSan, as the errors it reports have to be
fixed first.
Valgrind is still disabled, but can be enabled by setting
`env: VALGRIND=ON` for a job in `.travis.yml`.

Piping input into nvim causes the helptags generation to hang. For
example, the following does not work:
yes | nvim -c "helptags ."
The helptags are generated during installation with a command similar
to the one above, using CMake's execute_process to call nvim.
As execute_process does not use an intermediate shell, the following
will cause the installation to hang:
yes | make install
pacaur, an Arch Linux package helper, uses a similar command to
install packages [1], and thus can currently not be used to install
Neovim.
This commit adds a workaround to GenerateHelptags.cmake to circumvent
this problem.

For now, only install man pages matching "nvim*.1": we don't want to
install xxd.1 as it might conflict with that of a user's Vim
installation.

Jemalloc will be used if the cmake option `USE_JEMALLOC` is enabled(which is the
default). To avoid trouble with clang's ASAN, it is disabled by default if the
`SANITIZE` option is enabled.
Since jemalloc has thread cache for small objects, it fills the gap created by
removing klib memory pools.
The `xstrdup` funciton(memory.c) had to be reimplemented on top of `xmalloc` to
make it work with a custom allocator.
- Read TEST_TAG/TEST_FILTER env vars from cmake/RunTests.cmake. Setting these
environment variables will pass --tags/--filter to busted, which can used to
filter which tests are executed.
- Remove calls to nvim msgpack-rpc API outside tests. This removes the
requirement of having a static `clear` call in test/functional/helpers.lua
- Use the new busted command-line option "--lazy" to ensure the setup/teardown
hooks are only executed when a suite runs at least one test.
Now its possible to run/debug a single test like this:
```sh
TEST_FILTER='some test string' make test
```
Which will only run tests containing "some test string" in the title.
Another option is:
```sh
TEST_TAG=some-tag make test
```
After putting #some-tag into the test title. This also improves debugging
experience because there will be no unnecessary gdbserver instances whe GDB=1 is
passed.
This requires a couple of extra modules that are not installed by
default, and it requires capturing stdout of the tests--otherwise CMake
output is intermixed with the XML output of busted.
It turns out that Busted started cleaning the environment in 2.0rc5 as a
result of Olivine-Labs/busted#62. This, in turn, caused the ffi module
to be reloaded for each spec file, and LuaJIT doesn't appreciate it.
The net effect is an assertion error in LuaJIT.
By using the --helper feature of Busted, we can pre-load some modules
ahead of Busted and prevent it from reloading them--making LuaJIT happy
again.
On some systems, such as NetBSD, the gettext header is tucked under the
gettext directory in the system include area. Let's add a path suffix
to ensure we correctly discover the header on such systems.
It turns out that CMake always canonicalizes `CMAKE_INSTALL_PREFIX` to
an absolute path--if it's a relative path, it canonicalizes it relative
to the build directory. As a result, the only thing the DESTDIR and
relative directory check prevents is an installation into the root
directory since CMake strips the trailing slash, turning "/" into an
empty string. Let's just remove the check all together, since it cannot
accomplish what we intended.
It turns out that `file(INSTALL ...)` already accounts for `DESTDIR`, so
this wasn't creating the directory structure in the correct location.
Instead, we need to do our existence check with `DESTDIR`, but leave it
off when doing the install step.
While we're at it, add a check to make sure `ENV{DESTDIR}` is not being
used with a relative path, as that construct doesn't make much sense.
This fixes issue #1387 discovered while trying to make helptag
generation work correctly in #1381.
