* attempt to make asynchttpserver better; fixes#15925; [backport:1.0]
* better documentation
* fixes 'nim doc'
* makes test green again
* ported to FreeRTOS
* fixes the doc rendering
* Make IntSet an ordinal set OrdSet[A: Ordinal]
Backward compatibility with IntSet is maintained.
IntSet is an alias for OrdSet[int]
* move ordsets to new file, intsets exports it
* ordset, move to lib/std folder
* Fix `$` for ordsets and test cleanup
* Fix ordsets compilation in doc example
* Rename ordsets to packedsets
* Fix#8404 JS backend doesn't handle float->int type conversion
* handle conv to uint as cast, discard other cases
* limit to int32, times use int64
* toInt including tyInt64 break times timezones lib, ignore for now
* also affect to vm
* move to tests/misc/t8404.nim
* doAssertRaises now correctly handles foreign exceptions; now shows which exception is raised on mismatch
* nimscript now handles `Exception as e`
* remove catch-all doAssertRaises overload from this PR

Add a macro `enumLen` which is used to determine the number of items in
an enumeration type to the `typetraits.nim` module. Also, add unit tests
for it in the `ttypetraits.nim` module.

Make `requiresInit` pragma to work for distinct types in addition to
objects. Tagging of distinct types with `requiresInit` pragma was
already supported, but its impact wasn't applied. Now its behavior when
applied on distinct types is as follows.
Given the following distinct type definitions:
```nim
type
DistinctObject {.requiresInit, borrow: `.`.} = distinct MyObject
DistinctString {.requiresInit.} = distinct string
```
The following code blocks will fail to compile:
```nim
var foo: DistinctFoo
foo.x = "test"
doAssert foo.x == "test"
```
```nim
var s: DistinctString
s = "test"
doAssert s == "test"
```
But these ones will compile successfully:
```nim
let foo = DistinctFoo(Foo(x: "test"))
doAssert foo.x == "test"
```
```nim
let s = "test"
doAssert s == "test"
```
