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.

Apple doesn't have that.)

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.
