Replace most libsodium usage with Rust crates
We currently use four components of libsodium:
- Random byte generation
- BLAKE2b
- Ed25519
- ChaCha20Poly1305
This PR replaces the first three with equivalent logic from Rust crates:
- `rand_core::OsRng`
- `blake2b_simd`
- `ed25519-zebra`
- `libsodium` is still used for Ed25519 verification in the consensus rules until Canopy activation.
crypto_sign_verify_detached is still used within the consensus rules
until Canopy activation. ed25519-zebra generates signatures that are
valid under both pre- and post-Canopy rules (for our honest usage),
so we can use it to generate transaction signatures now. Then once
Canopy activates, we can remove the remaining usages of crypto_sign.
We only use the output of GetActiveFundingStreamElements and
GetActiveFundingStreams within Canopy contexts, but this makes it
explicit that funding streams are disabled before Canopy activation.
Remove 'jessie' (debian 8) from suites list in linux gitian descriptors
Debian 8 "jessie" support reached its end-of-life on June 30, 2020

Add support for logging fields in spans and events
Field values must be pointers to C strings, which in practice means that they
cannot be formatted inline (as the pointer must remain valid across the FFI).
This might be improved by future iterations of the macros.
`LogPrint()` is also moved to the DEBUG level, leaving `LogPrintf()` at INFO.
The X11 license specifically mentions the X Consortium as the party that the no-advertising clause applies to.

Improvements to tracing initialization
The refactor makes it easier to implement further tracing customisations.
We also now have spans for `zcashd` initialization and shutdown.
Update checksec.sh to slimm609/checksec.sh version 2.3.0
To verify against the upstream signature:
```
git clone https://github.com/slimm609/checksec.sh
cd checksec.sh
git checkout a6df608ac077689b2160e521db6601abc7b9e26e
openssl dgst -sha256 -verify checksec.pub -signature checksec.sig ${ZCASH_SRC}/qa/zcash/checksec.sh
```
This version has more thorough Fortify checking (using `--extended --fortify-file=`) and checks specific to Clang-compiled executables.
Give a better error message for transaction expiry
As mentioned in https://github.com/zcash/zcash/issues/3393, user gets an error when sending a tx while wallet not caught up. Here we give the user a better explanation of the possible error.
Add test for garbage memory in history nodes
Tests that garbage memory in history nodes smaller than `NODE_SERIALIZED_LENGTH` have no effect when computing the `HistoryRoot` hash.
Add libfuzzer support
- Added libfuzzer support to the build system in zcutil.
- Added UniValue::Read fuzzer, dict, corpus.
I made a slight change to the build.sh script so as to separate dependency building vs src building, just so that I can layer the docker containers for building over in another repo to speed up the continuous build processes that will want to build multiple fuzzers from the same commit.
Closes#4548
This will make it possible to de-duplicate some components of the
tracing configuration. The layers themselves cannot be fully
de-duplicated due to type system constraints (a Layer wraps a
Subscriber, and is itself a Subscriber typed on the one it wraps).
