0b440d9543 Apparently gcc 6 defines __cpp_aligned_new in C++14 mode, however no std::align_val_t is available there

079b886feb Add cmake option to specify whether warnings / errors are enabled by default. 
Currently warnings / errors are enabled by default in debug build.
Otherwise they could be enabled only via environmental variable or
API option call. Add possibility to specify the default during the
build time. This simplifies e.g. integration of the library into
bigger projects as no source changes would be required.

2f1fc1df5c Add xmalloc()-like functionality. 
xmalloc is a non-standard extension forcing malloc() to
abort should the memory allocation failed instead of returning a
null pointer. Such functionality is quite useful as it provides one
single point of error handling if the caller of malloc() does not
check the result (as it often does!) and segfault is ocurring somewhere
else. If more fine-grained control is necessary one could register a custom
error handler, however, this might not be an option while interposing.

a4ed63d127 Adresses pr #165 and issue #164 by @colesbury: 
On Mac OS, the thread-local _mi_default_heap may get reset before
_mi_thread_done is called, leaking the default heap on non-main threads.

Now the current default heap is also stored in mi_pthread_key (or mi_fls_key
on Windows). The _mi_thread_done function is called with this value.
