Summary:
This set of changes implements the following design: `ldb` will utilize `--path` parameter which can be used to specify a file name. Tool will then apply some heuristic to determine how to output the data properly. The design decision is not to probe the file content, but use file names to determine what dumping function to call.
Usage examples:
Understands that path points to a manifest file and dumps it.
`./ldb --path=/tmp/test_db/MANIFEST-000023 dump`
Understands that path points to a WAL file and dumps it.
`./ldb --path=/tmp/test_db/000024.log dump --header`
Understands that path points to a SST file and dumps it.
`./ldb --path=/tmp/test_db/000007.sst dump`
Figures out that none of the supported file types are applicable and outputs
an appropriate error message.
`./ldb --path=/tmp/cron.log dump`
Test Plan:
Basics:
git diff
make clean
make -j 32 commit-prereq
arc lint
More specific testing (done as part of commit-prereq, but can be iterated separately when making isolated changes):
make clean
make ldb
python tools/ldb_test.py
make rocksdb_dump
make rocksdb_undump
sh tools/rocksdb_dump_test.sh

Summary:
Added tests for two LDBCommands namely i) ManifestDumpCommand and ii) ListColumnFamiliesCommand.
+ Minor fix in the sscanf formatter (along relace C cast with C++ cast) + replacing localtime with localtime_r which is thread safe.
Test Plan: make all && ./tools/ldb_test.py

Summary: This is failing our tsan tests. Our new behavior is to fail DB::Open() if the requested compression is not available. The easiest fix is to make ldb_test not depend on compression.

Summary:
Priliminary diff to solicit comments.
Given DB path, dump all SST files (key/value and properties), WAL file and manifest
files. What command options do we need to support for this command? Maybe
output_hex for keys?
Test Plan: Create additional ldb unit tests.

Summary: Added a function/command to check the consistency of live files' meta data
Test Plan:
Manual test (size mismatch, file not exist).
Command test script.

Summary:
If the last byte of the timestamp is 0, the output value of the ttl db
can cut off earlier. Change to compare hex format instead.
Test Plan:
this does not happen consistently, but it did not fail after the last
100 runs
for i in {1..100}; do python ./tools/ldb_test.py; done

Summary: Added an option --count_delim=<char> which takes the given character as delimiter ('.' by default) and reports count of each row type found in the db
Test Plan:
1. Created test in file (for DBDumperCommand) rocksdb/tools/ldb_test.py which puts various key value pair in db and checks the output using dump --count_delim ,--count_delim="." and --count_delim=",".
2. Created test in file (for InternalDumperCommand) rocksdb/tools/ldb_test.py which puts various key value pair in db and checks the output using dump --count_delim ,--count_delim="." and --count_delim=",".
3. Manually created a database with several keys of several type and verified by running the command
./ldb db=<path> dump --count_delim="<char>"
./ldb db=<path> idump --count_delim="<char>"

Summary: ldb works with raw data from the database and needs to be aware of ttl-database to work with it meaningfully. '-ttl' option now tells it that. Also added onto the ldb_test.py test. This option may be specified alongwith put, get, scan or dump. There is no support to provide a ttl-value and it uses default forever because there is no use-case for this currently.
Test Plan: make ldb_test; python tools/ldb_test.py

Summary: ldb_test.py did a lot of assertFalse checks and displayed all the failed messages on the std output making it confusing to tell a successful from a failed run. Also many empty lines used to be needlessly printed. Also added some progression-"feel-good" lines in the tests
