708: Reduce memory usage of the MatchingWords structure r=ManyTheFish a=loiclec
# Pull Request
## Related issue
Fixes (partially) https://github.com/meilisearch/meilisearch/issues/3115
## What does this PR do?
1. Reduces the memory usage caused by the creation of a 10-word query tree by 20x.
This is done by deduplicating the `MatchingWord` values, which are heavy because of their inner DFA. The deduplication works by wrapping each `MatchingWord` in a reference-counted box and using a hash map to determine whether a `MatchingWord` DFA already exists for a certain signature, or whether a new one needs to be built.
2. Avoid the worst-case scenario of creating a `MatchingWord` for extremely long words that cannot be indexed by milli.

712: Fix bulk facet indexing bug r=Kerollmops a=loiclec
# Pull Request
## Related issue
Fixes (partially, until merged into meilisearch) https://github.com/meilisearch/meilisearch/issues/3165
## What does this PR do?
Fixes a bug where indexing certain numbers of filterable attribute values in bulk led to corrupted facet databases. This was due to a lossy integer conversion which would ultimately prevent entire levels of the facet database to be written into LMDB.
More specifically, this change was made:
```diff
- if cur_writer_len as u8 >= self.min_level_size {
+ if cur_writer_len >= self.min_level_size as usize {
```
I also checked other comparisons to `min_level_size` and other conversions such as `x as u8` in this part of the codebase.

707: Add all_obkv_to_json function r=Kerollmops a=GregoryConrad
## What does this PR do?
When embedding milli in an application (other than Meilisearch), it often makes sense to not use the `displayed_attributes` functionality and instead just use milli as a full document store. Thus, this PR adds a function, `all_obkv_to_json`, to supplement the already exposed `milli::obkv_to_json` so that those embedding milli *do not* need to deal with `displayed_attributes` if they don't need to.
~This PR also introduces a slight breaking change: `obkv_to_json` now accepts a reference to `obkv::KvReaderU16` instead of taking ownership of it. As far as I can tell, this seems like a change for the better (`obkv_to_json` only acts upon `obkv` rather than consuming it), but I can change it back if you so desire.~ (reverted in [935a724](935a724c57))

696: Fix Facet Indexing bugs r=Kerollmops a=loiclec
1. Handle keys with variable length correctly
Closes (partially) https://github.com/meilisearch/meilisearch/issues/3042
This issue is now easily reproducible with the updated fuzz tests, which now generate keys with variable lengths.
2. Prevent adding facets to the database if their encoded value does not satisfy `valid_lmdb_key`.
Closes (partially) https://github.com/meilisearch/meilisearch/issues/2743
This fixes an indexing failure when a document had a filterable attribute containing a value whose length is higher than ~500 bytes. For now, this fix is just meant to prevent crashes. Better handling of long values of filterable attributes will be handled in a separate PR.

699: Force vendoring of LMDB even if a system version is available r=Kerollmops a=dureuill
# Pull Request
## Related issue
Related to https://github.com/meilisearch/meilisearch/issues/3017: will fix once ported to milli and meilisearch.
## What does this PR do?
- Force using vendored version of LMDB
- **don't use lmdb master3 branch anymore**: this is a bit of a side effect of using a tag instead of branch for heed as a dependency, but it is wanted anyway for now as lmdb master3 was more of an experiment
- **modifies CI to run `cargo check` on the release rather than the debug artifacts**. This is an attempt to reduce the necessary disk space and avoid "out of space" failures.

693: use the lmdb-master.3 branch r=Kerollmops a=irevoire
After investigating https://github.com/meilisearch/meilisearch/issues/3017, we found out that it was due to lmdb and that, without any code change on our side, bumping using the lmdb-master-3 branch fix our issues.
But, we’re not really confident about what changed between the `mdb.master` and `mdb.master3` branches; thus this is a temporary change, and we hope we’ll be able to move to the new version of heed asap (either before the end of the pre-release or for the next release).
--------
The bug is hard to reproduce; I can reproduce it 100% of the time on my archlinux personal computer. But on a scaleway archlinux bare-metal machine, it doesn’t reproduce. It’s flaky on our test suite, but `@loiclec` was able to write a minimal test that reproduces it every time on macOS.
Basically, what happens is when there are multiple threads opening databases in a different directory at the same time.
If there are 10 or more threads running at the same time, lmdb starts throwing the `Invalid argument (os error 22)` error for no reason, we believe.
I would like to submit an issue to lmdb, but I don’t really have the time to write a test in C without heed currently.
`@hyc,` if you want to take a look at it, here is the repo that reproduces the issue on macOS: https://github.com/irevoire/heed-bug
