0b40ed5e70 Start re-refactoring the token bucket interface.
Begin by creating a lowest-level triple of the types needed to
implement a token bucket: a configuration, a timestamp, and the raw
bucket itself.

Note that for low-level buckets, the units of the timestamp and the
bucket itself are unspecified: each user can use a different type.

(This patch breaks check-spaces; a later patch will fix it)

03b96882de Rename token_bucket_t to token_bucket_rw_t.
This is a simple search-and-replace to rename the token bucket type
to indicate that it contains both a read and a write bucket, bundled
with their configuration.  It's preliminary to refactoring the
bucket type.

c376200f6a Add a new token-bucket backend abstraction, with tests
This differs from our previous token bucket abstraction in a few
ways:

  1) It is an abstraction, and not a collection of fields.
  2) It is meant to be used with monotonic timestamps, which should
     produce better results than calling gettimeofday over and over.

d8ef9a2d1e Expose a function that computes stamp units from msec.
(It turns out we can't just expose STAMP_TICKS_PER_SECOND, since
Apple doesn't have that.)

d3b9b5a3dd Remove windows log_from_handle as unused.

removed in 9df110cd72.  Its presence caused warnings on windows.

46795a7be6 Attempt to fix 32-bit clang builds, which broke with 31508a0abc
When size_t is 32 bits, the unit tests can't fit anything more than
4GB-1 into a size_t.

Additionally, tt_int_op() uses "long" -- we need tt_u64_op() to
safely test uint64_t values for equality.

Bug caused by tests for #24782 fix; not in any released Tor.

When size_t is 32 bits, doing "size_t ram; if (ram > 8GB) { ... }"
produces a compile-time warning.

31508a0abc Use less memory for MaxMemInQueues for machines with more than 8 GB of RAM.
This patch changes the algorithm of compute_real_max_mem_in_queues() to
use 0.4 * RAM iff the system has more than or equal to 8 GB of RAM, but
will continue to use the old value of 0.75 * RAM if the system have less
than * GB of RAM available.

This patch also adds tests for compute_real_max_mem_in_queues().

1295044dc8 Lift the list of default directory servers into their own file.
This patch lifts the list of default directory authorities from config.c
into their own auth_dirs.inc file, which is then included in config.c
using the C preprocessor.
