* Use Xenial as the base distribution
* Remove C++11 builds
* Add a lot more C++14 builds
* Add some C++17 builds
* Include newer versions of Clang and GCC
This also required some refactoring of how the pattern matching
works. This means that the concepts of include and exclude patterns
are no longer unified, with exclusion patterns working as just
negation of an inclusion patterns (which led to including hidden
tags by default, as they did not match the exclusion), but rather
both include and exclude patterns are handled separately.
The new logic is that given a filter and a test case, the test
case must match _all_ include patterns and _no_ exclude patterns
to be included by the filter. Furthermore, if the test case is
hidden, then the filter must have at least one include pattern
for the test case to be used.

This allows us to provide machine-readable listings through the
XMLReporter and it will also allow users to define their own listing
format that does whatever their own tools need.
Previously it returned the sum of listed things because ???. This
was completely useless and in many ways actively counterproductive
because of the success/failure conventions around exit codes.
Closes#1410
Previously, each warning suppression was self-contained, with its
own pair of `SUPPRESS_X_WARNING` and `UNSUPPRESS_X_WARNING` macros.
This had the obvious advantage of being self-containing, but it
also meant that if we needed to suppress more than one warning
in a single place, then we would manipulate the compiler's warning
state multiple times, even though logically we would only need one
layer.
The new way of suppressing warnings in macros is to push compiler's
warning state with `CATCH_INTERNAL_START_WARNINGS_SUPPRESSION` macro,
then disable whatever macros we need with the
`CATCH_INTERNAL_SUPPRESS_X_WARNINGS` macro, and then return to the
previous state using `CATCH_INTERNAL_STOP_WARNINGS_SUPPRESSION`.
The JUnit report is improved in that:
* The message shows the testing condition, not the result
* The actual message has similar output than the console one
Now it no longer tries to be this weird hybrid between an owning
and non-owning reference, and is only ever non-owning. This is also
reflected in its interface, for example `StringRef::isNullTerminated`
is now public, and `StringRef::c_str()` has the precondition that it
is true.
Overview of the changes:
* The `StringRef::m_data` member has been completely removed, as it
had no more uses.
* `StringRef::isSubstring()` has been made public and renamed to
`StringRef::isNullTerminated()`, so that the name reflects what the
method actually does.
* `StringRef::currentData()` has been renamed to `StringRef::data()`,
to be in line with common C++ containers and container-alikes.
* `StringRef::c_str()` will no longer silently make copies. It instead
has a precondition that `isNullTerminated()` is true.
* If the user needs a null-terminated string, they should use the
`std::string` conversion operator and call `c_str()` on the resulting
`std::string`.
* Some small optimizations in various places.
* Basic functionality is now `constexpr`.
Unless someone steps up to fix the long link times with a set of
unobtrusive changes, the recommended solution will remain "use a better
linker".

This should now properly handle small numbers which would previously
output something like `[0.00000000000000019, 0.00000000000000019]`,
which does not allow user to read the numbers properly.
Closes#1760
this warning was introduced by rework to support NTTPs
since we have implementation macro for NTTPs and normal template test cases
warning is going to be suppressed
Fixes#1762
