* feat: generate go1.21 files
* chore: update CI
* feat: add support for generic symbols in standard library packages
This is necessary to fully support go1.21 and beyond, which now
provide some generic packages such as `cmp`, `maps` or `slices`
in the standard library.
The principle is to embed the generic symbols in source form (as
strings) so they can be instantiated as required during interpretation.
Extract() has been modified to skip the generic types, functions and
constraint interfaces which can't be represented as reflect.Values.
A new stdlib/generic package has been added to provide the corresponding
source files as embedded strings.
The `Use()` function has been changed to pre-parse generic symbols as
doing lazy parsing was causing cyclic dependencies issues at compiling.
This is something we may improve in the future.
A unit test using `cmp` has been added.
For now, there are still some issues with generic stdlib packages
inter-dependencies, for example `slices` importing `cmp`, or when
generic types or function signatures depends on pre-compiled types
in the same package, which we will support shortly.

* update unsafe2 for go1.21, skip faky tests
In go1.21, the reflect rtype definition has been move to internal/abi.
We follow this change for maintainability, even if there is no layout
change (the go1.20 unsafe2 is compatible with go1.21).
We have isolated a few problematic tests which are failing sometimes
in go1.21, but work in go1.20, and also in go1.22. Those tests are
skipped if in go1.21. A preliminary investigation can not confirm that
something is wrong in yaegi, and the problem disappears with go1.22.
* add new wrapper for go1.21 package testing/slogtest
* add missing wrapper for go/doc/comment
* add support for slices generic package

Unsafe functions such as `unsafe.Alignof`, `unsafe.Offsetof` and `unsafe.Sizeof` can be used for type declarations early on during compile, and as such, must be treated as builtins returning constants at compile time. It is still necessary to explicitely enable unsafe support in yaegi.
The support of `unsafe.Add` has also been added.
Fixes#1544.
In addition:
- extract commmand now skips exported generics in runtime wrappers
- interp_consistent_test.go fixed for go1.18 and go1.19
- move minimal version of go compiler to go1.18
Note that this version is incompatible with go1.17 and before due
to the major changes in the stdlib go parser.
To be merged once go1.19 is officially released (not before).
The heuristic to generate a package name identifier was incorrect. Now for binary packages, the package identifier is obtained by a symbol, generated by extract, which contains the string argument of package statement in source file. This should ensure an always correct default package identifier.
Fixes#1095.
Offsetof returns the offset of a field in a struct. It is computed
during parsing at CFG, due to the constraint of operating on a
struct selector expression.
With this function, the support of 'unsafe' package is now
complete in yaegi.
Fixes#1062.
* chore: generate stdlib for go1.13
* chore: update CI configuration.
* fix: struct13 test is too dependent of the Go implementation.
* fix: disable test import4.go
