On Centos 6, you need to explicitely include linux/falloc.h which is
whele the FALLOC_FL_* flags are defined. Otherwise, the fallocate()
support test defined in build_detect_platform will fail.

Summary:
* Makefile (COMPILE_WITH_TSAN): Avoid a link failure by disabling
-pg when building with TSAN enabled.
Now that "make check" builds all $(PROGRAMS), it is linking
a few programs that were not normally linked before.
For example, this would fail to link with the following diagnostic:
COMPILE_WITH_TSAN=1 make -j40 log_and_apply_bench
CCLD log_and_apply_bench
ld: /usr/lib/../lib64/gcrt1.o: relocation R_X86_64_32S against `__libc_csu_fini' can not be used when making a shared object; recompile with -fPIC
/usr/lib/../lib64/gcrt1.o: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
Makefile:511: recipe for target 'log_and_apply_bench' failed
make: *** [log_and_apply_bench] Error 1
Since removing -pg is sufficient to get past this link
failure, and no one cares about profiling TSAN-enabled
binaries anyway, we will refrain from linking with -pg
when TSAN testing is enabled. Use a new variable, "pg"
which is set to "-pg" in most cases, but that is made
empty when COMPILE_WITH_TSAN is set.
Test Plan:
Now, this succeeds:
rm -f log_and_apply_bench
COMPILE_WITH_TSAN=1 make -j40 log_and_apply_bench

Summary:
* Makefile (check): Cause "make check" to build all $(PROGRAMS),
so that it verifies that the few benchmark-only source files that
not already built via "make check" do compile and link successfully.
Test Plan:
run "make clean; make check", and verify that
table/table_reader_bench.cc is now compiled.
Before, it was not, which led to an incomplete fix
for a build break.

Summary:
Improve ThreadStatusSingleCompaction in two ways:
1. Use SYNC_POINT to ensure compaction won't happen
before the test finishes its "Put Phase" instead of
using sleep.
2. In Put Phase, it continues until we have sufficient
number of L0 files. Note that during the put phase,
there won't be any compaction that consumes L0 files
because of item 1.

Summary:
In 3.10 the C++ code was extended with a MemEnv implementation. This
is now also available in RocksJava.
Changes:
- Extraced abstract super class Env
- Introduced RocksMemEnv
- Remove unnecessary disposeInternal method. The disposal of the default environment is managed by C++ so there needs to be no disposeInternal method in Java.
- Introduced a RocksMemEnvTest, which is aligned with the C++ equivalent.
