Old version doesn't support debug information for ELF produced by modern compilers
It appears like an error:
> unrecognized DWARF version in .debug_info at 6
> no debug info in ELF executable
which causes:
> No debug information available for stacktrace. You should add debug information and then run
And backtraces are not shown on linux even if debug infos here.
With this fixes output as expected:
```
std::terminate() called due to unhandled exception

```
We use pkg-config where we can, which generally replaces libtool at a
higher level and does not have the same downsides as libtool. These
archives sit in our depends tree with no purpose and pollute the final
bitcoin build with massive overlinking.
```
See [here](https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Handling_Libtool_Archives) for an explanation of the various problems libtool archives can cause.
Unrelated in every way except in spirit: `-D__LIBTOOL_IS_A_FOOL__`!!

* Add libbacktrace to depends
This is currently only useful to extract symbols. It fails to gather
stacktraces when compiled with MinGW, so we can only use it to get symbol
information from a stack trace which we gathered outside of libbacktrace.
* Add -mbig-obj to CXXFLAGS for MinGW builds
* Implement stacktraces for C++ exceptions
This is a hack and should only be used for debugging. It works by wrapping
the C++ ABI __wrap___cxa_allocate_exception. The wrapper records a backtrace
and stores it in a global map. Later the stacktrace can be retrieved with
GetExceptionStacktraceStr.
This commit also adds handlers to pretty print uncaught exceptions and
signals.
* Use GetPrettyExceptionStr for all unhandled exceptions
* Use --enable-stacktraces in CI for linux32/linux64
* Register exception translators to pretty print exceptions in unit tests
* Catch and print python exceptions when stopping nodes
Otherwise the code at the bottom is never executed when nodes crash,
leading to no output of debug.log files on Travis.
* Remove now unneeded/unused TestCrash methods
