Summary:
Few corrections with no functional change:
- replacing `%zd` with `%zu` all around: the values are unsigned
- prefer `MAP_ANONYMOUS` to `MAP_ANON` (it's deprecated)
- remove the unused `enum LinkerInitialized`
- mark a parameter as `UNUSED` in Fuchsia's `getRandom`
- correct the casing of a variable and use `nullptr` instead of 0 for
pointers in `list.h`
- reorder some `typedef` to be consistent between `signed` and
`unsigned`

Summary:
The Secondary allocator wraps the platform allocation primitives. It is
meant to be used for larger sizes that the Primary can't fullfill, as
it will be slower, and sizes are multiple of the system page size.
This also changes some of the existing code, notably the opaque
platform data being passed to the platform specific functions: we can
shave a couple of syscalls on Fuchsia by storing additional data (this
addresses a TODO).

Summary:
This is the initial check-in for the Standalone version of Scudo.
The project is initially going to live in scudo/standalone then will
replace scudo. See http://lists.llvm.org/pipermail/llvm-dev/2019-January/129113.html
for details.
This initial CL is meant to lay out the project structure, of both
code & tests, providing a minimal amount of functionalities, namely
various definitions, some atomic helpers and an intrusive list.
(empty.cc is just here to have a compilation unit, but will go away
in the upcoming CLs).
Initial support is restricted to Linux i386 & x86_64 in make files
and will be extended once things land & work.
We will grow organically from here, adding functionalities in limited
amounts.
