util: teach lrucachedict to enforce a max total cost

Now that lrucachedict entries can have a numeric cost associated
with them and we can easily pop the oldest item in the cache, it
now becomes relatively trivial to implement support for enforcing
a high water mark on the total cost of items in the cache.

This commit teaches lrucachedict instances to have a max cost
associated with them. When items are inserted, we pop old items
until enough "cost" frees up to make room for the new item.

This feature is close to zero cost when not used (modulo the insertion
regressed introduced by the previous commit):

$ ./hg perflrucachedict --size 4 --gets 1000000 --sets 1000000 --mixed 1000000

I reckon the slight slowdown on insert is due to added if checks.

For caches with total cost limiting enabled:

$ hg perflrucachedict --size 4 --gets 1000000 --sets 1000000 --mixed 1000000 --costlimit 100
! gets w/ cost limit

! gets w/ cost limit

The functions we're benchmarking are slightly different, which could
move numbers by a few milliseconds. But the slowdown on insert is too
great to be explained by that. The slowness is due to insert heavy
operations needing to call popoldest() repeatedly when the cache is
at capacity. The next commit will address this.

Note for future hackers of patchbomb: this file is a bit heavy on
wildcards in test expectations due to how many things like hostnames
tend to make it into outputs. As a result, you may need to perform the
following regular expression substitutions:
