Allow replacing the GSlice allocator with jemallocslice-jemalloc
The jemalloc allocator implementation comes from the BSD world, and it's
used in various places, including:
* Mozilla
* Rust
* Android
* Cassandra
* MariaDB
* Redis
More info: http://jemalloc.net
Currently, support is enabled by default on Linux, but you have to opt
in using `G_SLICE=use-jemalloc`.
