Without exposing `trace`, we can't set a target to enable tracing from
out of go-git.

plumbing: Optimise memory consumption for filesystem storage

Previously, as part of building the index representation, the resolveObject
func would create an interim plumbing.MemoryObject, which would then be
saved into storage via storage.SetEncodedObject. This meant that objects
would be unnecessarily loaded into memory, to then be saved into disk.
The changes streamlines this process by:
- Introducing the LazyObjectWriter interface which enables the write
operation to take places directly against the filesystem-based storage.
- Leverage multi-writers to process the input data once, while targeting
multiple writers (e.g. hasher and storage).
An additional change relates to the caching of object info children within
Parser.get. The cache is now skipped when a seekable filesystem is being
used.
The impact of the changes can be observed when using seekable filesystem
storages, especially when cloning large repositories.
The stats below were captured by adapting the BenchmarkPlainClone test
to clone https://github.com/torvalds/linux.git:
pkg: github.com/go-git/go-git/v5
cpu: Intel(R) Core(TM) i9-10885H CPU @ 2.40GHz
│ /tmp/old │ /tmp/new │
│ sec/op │ sec/op vs base │
PlainClone-16 41.68 ± 17% 48.04 ± 9% +15.27% (p=0.015 n=6)
│ /tmp/old │ /tmp/new │
│ B/op │ B/op vs base │
PlainClone-16 1127.8Mi ± 7% 256.7Mi ± 50% -77.23% (p=0.002 n=6)
│ /tmp/old │ /tmp/new │
│ allocs/op │ allocs/op vs base │
PlainClone-16 3.125M ± 0% 3.800M ± 0% +21.60% (p=0.002 n=6)
Notice that on average the memory consumption per operation is over 75%
smaller. The time per operation increased by 15%, which may actual be less
on long running applications, due to the decreased GC pressure and the
garbage collection costs.

This adds UpdateServerInfo along with a new go-git command to generate
info files to help git dumb http serve refs and their objects.
This also updates the docs to reflect this.

Improve handling of remote errors
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
Instead of simply returning the first line that the remote returned,
go-git now actively searches all of stderr for lines that may contain
a more actionable error message and returns that.
In addition, this change adds a case to map the GitLab-specific error
message to an ErrRepositoryNotFound error.

Unfortunately the original variant makes some incorrect typing
assumptions about commit-graphs which make handling graph chains
difficult to do correctly. This creates a new subpackage and deprecates
the old one. It then adds support commit graph chains.

Since the build-tag sha256 was introduced the commit graph code should
be switched to use hash.Size and only use a graph if it has the correct
hash version for the version of go-git that is built.

For diagnostics reasons we want to surface error messages coming from VCS providers.
That's why we introduce the reason field to Err struct in http package.
This field can be used by an end user of the library in order to better understand failures.

Git v2.41.0 comes with [changes](https://github.com/git/git/commit/933e3a4ee205353d8f093d5dfcd226fa432c4e58)
that breaks go-git's assumptions for when detecting empty repositories.
Go-git expects a flush instead of the first hash line. Instead, a dummy capabilities^{}
with zero-id is returned. The change aims to allow for identifying
the object format even when cloning empty
repositories.

Add support for custom HTTP and HTTPS proxies for each session.
The tests require server certificate and a matching private key to be
able to run a TLS server and test HTTPS proxy functionality. The cert
and the key are stored in `plumbing/transport/http/testdata/certs` and
were generated using the following command:
`openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout server.key -out server.crt`
Note: All details were left empty, except for the FQDN for which
example.com was used.

objects
Refactor the in-built http transport to cache the underlying http
transport objects mapped to its specific options for each Git transport
object. This lets us reuse the transport for a specific set of configurations
as recommended. (ref: https://pkg.go.dev/net/http#Transport)
If there are no transport specific options provided, the default
transport is used.
