Read more about k-anonymity [here](https://en.wikipedia.org/wiki/K-anonymity). We implement this feature in the monero daemon for transactions
by providing a "Txid Template", which is simply a txid with all but `num_matching_bits` bits zeroed out, and the number `num_matching_bits`. We add an operation to `BlockchainLMDB` called
`get_txids_loose` which takes a txid template and returns all txids in the database (chain and mempool) that satisfy that template. Thus, a client can
ask about a specific transaction from a daemon without revealing the exact transaction they are inquiring about. The client can control the statistical
chance that other TXIDs (besides the one in question) match the txid template sent to the daemon up to a power of 2. For example, if a client sets their `num_matching_bits`
to 5, then statistically any txid has a 1/(2^5) chance to match. With `num_matching_bits`=10, there is a 1/(2^10) chance, so on and so forth.

Removed version 2 onion addresses as they're deprecated from TOR and updated I2P/Tor Stream Used Twice section to reference tweets relevant to section.
Fixed grammatical errors and changed the wording within the Wallet RPC section to better explain the differences between a I2P hidden service and a TOR hidden service.
ea053b6 Update tests/hash/main.cpp (0xFFFC0000)
6bae913 Tests: Add blake2b Test Cases for hash testing. * Adding blake2b test function to src/tests/hash * New files for testvector. * Adding the test to CMakeLists.txt * Adding brief documentation for the test. (0xFFFC0000)
All the files in src/platform are currently unused and unnecessary. See below:
* `mingw/alloca.h`: unused throughout project
* `msc/sys/param.h`:
1. In `fix_darwin.patch`, `sys/param.h` is well-defined to be used only in OpenBSD environment
2. `int-util.h` already handles when `sys/param.h` is not present and injects its own values
3. `db_drivers/liblmdb/mdb.c` is a similar situation: already explicity handles different platforms
4. `src/crypto/chacha.h` uses `int-util.h` for endianness context
* `msc/alloca.h`: unused
* `msc/inline_c.h`: not needed. the `inline` keyword is supported for C99 I believe, and certainly for C11, C14+
* `msc/stdbool.h`: `stdbool.h` is standard since C99, and MSVC has supported it for a long time (~10 years)
