We're including a couple of standard headers like <stdint.h> in a bunch
of locations, which makes it hard for a project to plug in their own
logic for making required functionality available. For us this is for
example via "compat/posix.h", which already includes all of the system
headers relevant to us.
Introduce a new "reftable-system.h" header that allows projects to
provide their own headers. This new header is supposed to contain all
the project-specific bits to provide the POSIX-like environment, and some
additional supporting code. With this change, we thus have the following
split in our system-specific code:
- "reftable/reftable-system.h" is the project-specific header that
provides a POSIX-like environment. Every project is expected to
provide their own implementation.
- "reftable/system.h" contains the project-independent definition of
the interfaces that a project needs to implement. This file should
not be touched by a project.
- "reftable/system.c" contains the project-specific implementation of
the interfaces defined in "system.h". Again, every project is
expected to provide their own implementation.

The license headers used across the reftable library doesn't follow our
typical coding style for multi-line comments. Fix it.

Refactor the interfaces exposed by `struct reftable_table` and `struct
reftable_iterator` such that they support iterator reuse. This is done
by separating initialization of the iterator and seeking on it.
