Summary:
See the previous diff. As part of migrating away from IndexFilter. There needs
to be a way to filter commands by absolute clock time using pattern matching
against Events. To achieve that, add the timestamp field to Start and Finish
events.

Summary:
The existing query API `filter` has 2 issues:
- It does querying and filtering together, making it hard to express certain
queries. For example: "for commands taking more than 10 seconds, get all
network requests used by those commands".
- The `IndexFilter` abstraction overlaps with `pattern`s. `IndexFilter` is
built upon the `Entry` structure, and does not work for `Event`s. In the
future, we want a `Event::Tags` to tag commands, and build indexes on it.
That's not very compatible with `IndexFilter`.
To address the issues, I'm going to:
- Decouple querying and filtering by splitting it into 2 methods glued by
`SessionId`s.
- Deprecate `IndexFilter`. Make `patterns` the only way to filter entries.
- Add dedicated indexes for certain events.
This diff adds the related APIs towards that direction.

Summary:
This updates the `RustStaticLibrary.cmake` file to download vendored
`crates.io` crates only once, rather than once per library. It also now
downloads them into the build directory, rather than into the source
directory.
This can probaly still be improved more in the future: the vendored crates
should probably just be treated as a top-level getdeps manifest entry.
Currently if multiple projects build rust static libraries we will still end
up downloading the vendored crates once per project.

Summary:
Edenapi uses a group of impls like the following as the canonical way to construct ApiError.
```
impl From<Context<ApiErrorKind>> for ApiError {
```
Downstream code would write:
```
use failure::ResultExt;
let stream_trees = config
.get_or_default("edenapi", "streamtrees")
.context(ApiErrorKind::BadConfig("edenapi.streamtrees"))?;
```
This relies on the way that ResultExt::context returns a unique type that is different from failure::Error.
This diff introduces a dedicated extension trait to allow the same code in the caller to continue to work even without a failure::Context<T> type, which will be required for dropping our dependency on failure::Fail and failure.
```
pub trait ApiErrorContext<T> {
fn context(self, kind: ApiErrorKind) -> ApiResult<T>;
}
```
We also introduce a public constructor for ApiError and replace indirect construction that used to look like this:
```
error.context(ApiErrorKind::Curl).into()
```
with this instead:
```
ApiError::new(ApiErrorKind::Curl, error)
```
which is the same number of characters but clearer. The argument order matches [std::io::Error::new](https://doc.rust-lang.org/std/io/struct.Error.html#method.new).

Summary:
Now that fmt is available in Folly builds (D14813810), use it to reduce binary code size in Folly Logger. This is done by moving most of the formatting logic behind the type-erased `vformat` API. Previously it was instantiated for all combinations of formatting argument types used in calls to `FB_LOGF` and `XLOGF` in a program.
The effect of this change can be illustrated by looking at symbol sizes as given by `nm -S -td` for the following test function:
```
void test_log() {
FB_LOGF(logger, WARN, "num events: {:06d}, duration: {:6.3f}", 1234, 5.6789);
}
```
compiled in `opt` mode.
`nm` before:
```
0000000004236736 0000000000000231 T test_log()
0000000004236992 0000000000001002 W std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > folly::LogStreamProcessor::formatLogString<int, double>(folly::Range<char const*>, int const&, double const&)
```
`nm` after:
```
0000000004237536 0000000000000231 T test_log()
0000000004237792 0000000000000251 W std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > folly::LogStreamProcessor::formatLogString<int, double>(folly::Range<char const*>, int const&, double const&)
0000000004238048 0000000000000740 W folly::LogStreamProcessor::vformatLogString[abi:cxx11](folly::Range<char const*>, fmt::v5::format_args, bool&)
```
Before we had one 1002 byte instantiation of `formatLogString<int, double>`. With this change it was reduced 4x to 251 bytes and non-template function `vformatLogString` was added which is shared among all logging calls. The size of `test_log` remained unchanged. There are even bigger savings from Folly Formatter instantiations which are no longer needed, e.g.
```
0000000004238032 0000000000001363 W _ZNK5folly13BaseFormatterINS_9FormatterILb0EJRKiRKdEEELb0EJS3_S5_EEclIZNKS7_8appendToINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEENSt9enable_ifIXsr12IsSomeStringIT_EE5valueEvE4typeERSH_EUlNS_5RangeIPKcEEE_EEvSK_
```
So in total this change results in ~5x per-call/instantiation binary size. It is possible to reduce binary size even further but it is not done in the current diff to keep it manageable.
In addition to binary size improvements, switching to fmt will potentially
* allow catching errors in format strings at compile time,
* simplify future migration to C++20 [`std::format`](http://eel.is/c++draft/format).

Summary: The commit timestamps in Git have second granularity. As a result, sometimes multiple succeeding commits have numerically equivalent timestamps. This means that sorting by timestamp may not result in the correct ordering of commits. This is particularly true because the sort we use is a stable sort, which means that commits with the same timestamp must go into the sort in ascending commit history order to have the correct order coming out of the sort. This commit updates the log that generates the list to use ascending commit order rather than descending.

with:
```
use thiserror::Error;

#[error("something failed {0} times")]

```
The former emits an implementation of failure 0.1's `Fail` trait while the latter emits an impl of `std::error::Error`. Failure provides a blanket impl of `Fail` for any type that implements `Error`, so these `Error` impls are strictly more general. Each of these error types will continue to have exactly the same `Fail` impl that it did before this change, but now also has the appropriate `std::error::Error` impl which sets us up for dropping our various dependencies on `Fail` throughout the codebase.

Summary:
`globset` supports multiple matching strategies, including literal prefix
(backed by AhoCorasick), or regexp, etc.
In theory patterns like `foo/**` (where `*` cannot match `/`) can use `foo`
prefix strategy. However, the implementation detail of `globset` wouldn't
accept it as a prefix. But `foo/*` (where `*` can match `/`) can be treated as
a prefix. Transform the former pattern to the latter to hint `globset` to use
the optimal strategies.

This diff is preparation for migrating off of failure::Fail / failure::Error for errors in favor of errors that implement std::error::Error. The Fallible terminology is unique to failure and in non-failure code we should be using Result<T>. To minimize the size of the eventual diff that removes failure, this codemod replaces all use of Fallible with Result by:
- In modules that do not use Result<T, E>, we import `failure::Fallible as Result`;
- In modules that use a mix of Result<T, E> and Fallible<T> (only 5) we define `type Result<T, E = failure::Error> = std::result::Result<T, E>` to allow both Result<T> and Result<T, E> to work simultaneously.
