Final Cleanup (hopefully) and including some performance numbers.
...
I microbenchmarked the storage queue standalone. i.e. the set and clearrange mutations
were performed solely at the in-memory storage queue. No other FDB components were involved
in this test. And hence the numbers presented here the best case numbers.
Test setup:
- 100M mutations: about 5% clearRange and 95% set mutations
- 100M rangeReads
- Keys/Values generated using deterministicRandom()
- A new version generated for each mutation (i.e. it's an extreme version test)
Performance comparison between std::map and std::deque for VersionedMap"
std::map std::deque
Time to perform the mutations 220.066 218.784
Time to perform buffered readRange 184.423 171.578

Replace g_random and g_nondeterministic_random with functions deterministicRandom() and nondeterministicRandom() that return thread_local random number generators. Delete g_debug_random and trace_random. Allow only deterministicRandom() to be seeded, and require it to be seeded from each thread on which it is used.

Added 96-byte FastAllocator

Since storage queue nodes account for a large portion of memory usage,
we can save space by only allocating 96 bytes instead of 128 bytes for
each node.

Adjust all includes to be relative to the root.
...
Remove the use of relative paths. A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h". Adjust so that every include references such a header with the
latter form.

Attempt to normalize trace events:
...
* Detail names now all start with an uppercase character and contain no underscores. Ideally these should be head-first camel case, though that was harder to check.
* Type names have the same rules, except they allow one underscore (to support a usage pattern Context_Type). The first character after the underscore is also uppercase.
* Use seconds instead of milliseconds in details.
Added a check when events are logged in simulation that logs a message to stderr if the first two rules above aren't followed.
This probably doesn't address every instance of the above problems, but all of the events I was able to hit in simulation pass the check.
