in 64-bit.
Currently, a signed off_t type is being used for the following
interfaces for both offset and the length in bytes:
* `Allocate`
* `RangeSync`
On Linux `off_t` is automatically either 32 or 64-bit depending on
the platform. On Windows it is always a 32-bit signed long which
limits file access and in particular space pre-allocation
to effectively 2 Gb.
Proposal is to replace off_t with uint64_t as a portable type
always access files with 64-bit interfaces.
May need to modify posix code but lack resources to test it.
Summary:
Parallel writes will only be possible for certain combinations of
flags and WriteBatch contents. Traversing the WriteBatch at write time
to check these conditions would be expensive, but it is very cheap to
keep track of when building WriteBatch-es. When loading WriteBatch-es
during recovery, a deferred computation state is used so that the flags
never need to be computed.
Test Plan:
1. add asserts and EXPECT_EQ-s
2. make check

Summary:
Scoped anonymous enums seem to be better supported than static
constexpr at the moment, so this diff replaces the latter with the former.
Also, this diff removes an incorrect inclusion of pthread.h. MSVC build
was broken starting with D50439.
Test Plan:
1. build
2. observe proper skiplist behavior by absence of pathological slowdown
3. push diff to tmp_try_windows branch to tickle AppVeyor
4. wait for contbuild before committing to master

Summary:
Using a TLS random instance for skiplist makes it smaller
(useful for hash_skiplist_rep) and prepares skiplist for concurrent
adds. This diff also modifies the branching factor math to avoid an
unnecessary division.
This diff has the effect of changing the sequence of skip list node
height choices made by tests, so it has the potential to cause unit
test failures for tests that implicitly rely on the exact structure
of the skip list. Tests that try to exactly trigger a compaction are
likely suspects for this problem (these tests have always been brittle to
changes in the skiplist details). I've minimizes this risk by reseeding
the main thread's Random at the beginning of each test, increasing the
universal compaction size_ratio limit from 101% to 105% for some tests,
and verifying that the tests pass many times.

PowerShell seems to have a hard time when a flood of async tasks is
scheduled at the same time.
I speculated that WaitForMultipleObjects() in Windows can only take up
to 64 process handles and if you want to handle more than you should write
some additional code which can be sub-optimal. I.e to implement Wait-Job -Any.
I decided to test that suggestion and introduced a $Concurrency parameter with a default value of 62.
So in the new version the script fires up up to $Concurrency value
and wait for anything to complete before starting any more processes.
This improved matters greatly. Individual tests against ramdrive now
run in 8 minutes and all of the 200+ db_tests run in 9 minutes with concurrency
values of 8-16. About 48 is required to load a CPU on my box running against HD
but that does not improve running times much.
Other changes include respect -EnableJE for the individual test exes.
Enforce exclusions for the individual tests.

Summary:
MyRocks testing found an issue that while iterating over keys
that are outside the prefix, sometimes wrong results were seen for keys
outside the prefix. We now tighten the range of keys seen with a new
read option called prefix_seen_at_start. This remembers the starting
prefix and then compares it on a Next for equality of prefix. If they
are from a different prefix, it sets valid to false.

Summary:
This diff is a first step towards an iterator based interface for the
SearchRadial method which replaces a vector of GeoObjects with an
iterator for GeoObjects. This diff works by just wrapping the iterator
for the encapsulated vector of GeoObjects. A future diff could extend
this approach by defining an interator in terms of the underlying
iteration in SearchRadial which would then remove the need to have
an in-memory representation for all the matching GeoObjects.
