Need to return the same error structure/content as regular Go for
net.Conn Read/Write operations. Found/fixed when testing deadlines
on Read/Write operations.
This PR adds a network device driver model called netdev. There will be a companion PR for TinyGo drivers to update the netdev drivers and network examples. This PR covers the core "net" package.
An RFC for the work is here: #tinygo-org/drivers#487. Some things have changed from the RFC, but nothing major.
The "net" package is a partial port of Go's "net" package, version 1.19.3. The src/net/README file has details on what is modified from Go's "net" package.
Most "net" features are working as they would in normal Go. TCP/UDP/TLS protocol support is there. As well as HTTP client and server support. Standard Go network packages such as golang.org/x/net/websockets and Paho MQTT client work as-is. Other packages are likely to work as-is.
Testing results are here (https://docs.google.com/spreadsheets/d/e/2PACX-1vT0cCjBvwXf9HJf6aJV2Sw198F2ief02gmbMV0sQocKT4y4RpfKv3dh6Jyew8lQW64FouZ8GwA2yjxI/pubhtml?gid=1013173032&single=true).
Go 1.19 started reformatting code in a way that makes it more obvious
how it will be rendered on pkg.go.dev. It gets it almost right, but not
entirely. Therefore, I had to modify some of the comments so that they
are formatted correctly.
Some source code wasn't part of `FMT_PATHS` so wasn't checked for
correct formatting. This change includes all this source code and
excludes cgo/testdata because it contains files that can't be parsed.
internal/itoa wasn't around back in go 1.12 days when tinygo's syscall/errno.go was written.
It was only added as of go 1.17 ( https://github.com/golang/go/commit/061a6903a232cb868780b )
so we have to have an internal copy for now.
The internal copy should be deleted when tinygo drops support for go 1.16.
FWIW, the new version seems nicer.
It uses no allocations when converting 0,
and although the optimizer might make this moot, uses
a multiplication x 10 instead of a mod operation.
