Summary:
EspanId and tracing::span::Id had From/Into implementations that allowed them to be treated as
equivalent when they shouldn't be. This allowed for a subtle but where TracingData::record was
receiving an EspanId where the id was some huge u64 from a tracing::span::Id, when instead that
huge u64 should've been mapped to the real EspanId via the id_map.
Ideally we'd treat EspanId and the tracing Id separately, but the TracingCollector Subscriber
implementation relies on this. Since it controls span creation it can guarantee that all Id's are safely
convertible to EspanId.

Summary:
Limit the span or event count that a callsite can log so we can handle highly
repetitive calls. This is similar to D23307793 (d8e775f423) but applies to the Rust tracing

This new crate is part of the new telemetry / logging effort. Its input is

Summary:
This setup is more extendable than the TracingData focused approach. We can
more easily add new functionality using the Subscriber list.
The approach taken here to introduce the new collector tries to maintain
existing functionality. We can then move various logic to their own
Subscribers.

Summary:
Generated by formatting with rustfmt 2.0.0-rc.2 and then a second time with fbsource's current rustfmt (1.4.14).
This results in formatting for which rustfmt 1.4 is idempotent but is closer to the style of rustfmt 2.0, reducing the amount of code that will need to change atomically in that upgrade.
---
*Why now?* **:** The 1.x branch is no longer being developed and fixes like https://github.com/rust-lang/rustfmt/issues/4159 (which we need in fbcode) only land to the 2.0 branch.

Summary:
Some functions might be called very frequently. For example,
`phases.phasecache.loadphaserevs` might be called 100k+ times.
That makes the tracing data harder to process.
Limit the count of spans to 1k by default so the data is cheaper to process,
and some highly repetitive cases can now be reasoned about. Note the limit
is only put on static Span Ids. If a span uses dynamic metadata or ask for
different Span Ids each time, they will not be limited.
In debugshell,
td = %trace repo.revs('smartlog()')
len(td.serialize())
dropped from 6MB to 0.87MB.
It's also possible to reason about:
td = %trace len(repo.revs('ancestors(.)'))
in debugshell (taking 30s, 98KB serialized, vs 21s without tracing), while
previously the result would be too large to show (`%trace` just hangs).
