Implements view tags as proposed by @UkoeHB in MRL issue
https://github.com/monero-project/research-lab/issues/73
At tx construction, the sender adds a 1-byte view tag to each
output. The view tag is derived from the sender-receiver
shared secret. When scanning for outputs, the receiver can
check the view tag for a match, in order to reduce scanning
time. When the view tag does not match, the wallet avoids the
more expensive EC operations when deriving the output public
key using the shared secret.
* `IWallet.h` hasn't been touched since 2014, and has been replaced by `src/wallet/api/wallet2_api.h`
* `INode.h` is in a similar situation with `src/p2p/net_node.h`
Currently working on an EPEE [ser/de]ialization library for Rust and at first glance, EPEE seemed to have support for optional wrappers. However, after looking into it, this feature appears to be half-baked and unused. Furthermore, adding support for optional values would be better suited to implement at the storage level, in my opinion. That would make parsing DOMs easier and less error-prone. If anyone is currently using this code, please comment. Thanks!

The integrated address functional test fails in the workflows due
to an assertion for missing payment id that is no longer needed.
Remove the assertion and update the assertion count.

- grab an lmdb db_rtxn_guard to ensure consistent data from the db
- fixed on_getblockhash error resp when requested height >= blockchain height
- left functions that read shared memory untouched for now
It avoids dividing by 8 when deserializing a tx, which is a slow
operation, and multiplies by 8 when verifying and extracing the
amount, which is much faster as well as less frequent
* Remove `match_string()`, `match_number()`, and `match_word()`
* Remove `match_word_with_extrasymb()` and `match_word_til_equal_mark()`
* Adapt unit test for `match_number()` to `match_number2()`
* Adapt unit test for `match_string()` to `match_string2()`
Note: the unit tests were testing for the old version of the functions, and
the interfaces for these functions changed slightly, so I had to also edit
the tests.

Additional changes during review:
* Explicitly set up is_[float/signed]_val to be changed before each call
* Structify the tests and fix uninitialized variables
In this repo, `boost::interprocess` was being used soley to make `uint32_t` operations atomic. So I replaced each instance of
`boost::interprocess::ipcdetail::atomic(...)32` with `std::atomic` methods. I replaced member declarations as applicable. For example,
when I needed to change a `volatile uint32_t` into a `std::atomic<uint32_t>`. Sometimes, a member was being used a boolean flag, so
I replaced it with `std::atomic<bool>`.
You may notice that I didn't touch `levin_client_async.h`. That is because this file is entirely unused and will be deleted in PR monero-project#8211.
Additional changes from review:
* Make some local variables const
* Change postfix operators to prefix operators where value was not need
