I tried `incl` `tfHasAsgn` to nontrivial assignment, but that solution
seems to break too many things. Instead, in this PR, `passCopyToSink`
now checks nontrivial assignment
Because `prevFields` and `currentFields` have been already quoted by
`'`, no need to add another.
The error message was
```
The fields ''x'' and ''y'' cannot be initialized together, because they are from conflicting branches in the case object.
```
fixes#25117
errors on `requiresInit` of `result` if it is used before
initialization. Otherwise
```nim
# prevent superfluous warnings about the same variable:
a.init.add s.id
```
It produces a warning, and this line prevents it from being recognized
by the `requiresInit` check in `trackProc`

It changed `formatSize` outputs from some inputs, so some of existing
test code related to it need to be updated.
Sorry, I didn't know `tests/destructor/tnewruntime_strutils.nim` has
tests calls `formatSize`.
- Added support for SOCKS5h (h for proxy-side DNS resolving) to
httpclient
- Deprecated `auth` arguments for `newProxy` constructors, for auth to
be embedded in the url.
Unfortunately `http://example.com` is not currently reachable from
github CI, so the tests fail there for a few days already, I'm not sure
what can be done here.

```nim
var f = 751.0
echo f.int8
```
In this case, `int8(float)` yields different numbers for different
optimization levels, since float to int conversions are undefined
behaviors. In this PR, it mitigates this problem by conversions to same
size integers before converting to the final type: i.e.
`int8(int64(float))`, which has UB problems but is better than before
fixes#25007
```nim
proc setLengthSeqUninit(s: PGenericSeq, typ: PNimType, newLen: int, isTrivial: bool): PGenericSeq {.
compilerRtl.} =
```
In this added function, only the line `zeroMem(dataPointer(result,
elemAlign, elemSize, newLen), (result.len-%newLen) *% elemSize)` is
removed from `proc setLengthSeqV2` when enlarging a sequence.
JS and VM versions simply use `setLen`.
A function with an illegal parameter name like
```nim
proc myproc(type: int) =
echo type
```
would uninformatively fail like so:
```nim
tkeywordparam.nim(1, 13) Error: expected closing ')'
```
This commit makes it return the following error:
```nim
tkeywordparam.nim(1, 13) Error: 'type' is a keyword and cannot be used as a parameter name
```

Reworked closureiter transformation.
- Convolutedly nested finallies should cause no problems now.
- CurrentException state now follows nim runtime rules (pushes and pops
appropriately), and mimics normal code, which is somewhat buggy, see
#25031
- Previously state optimization (removing empty states or extra jumps)
missed some opportunities, I've reimplemented it to do everything
possible to optimize the states. At this point any extra states or jumps
should be considered a bug.
The resulting codegen (compiled binaries) is also slightly smaller.
**BUT:**
- I had to change C++ reraising logic, see expt.nim. Because with
closure iters `currentException` is not always in sync with C++'s notion
of current exception. From my tests and understanding of C++ runtime
there should not be any problems, but I'm only 99% sure :)
- I've reused `nfNoRewrite` flag in one specific case during the
transformation. This flag is also used in term-rewriting logic. Again,
99% sure, these 2 scenarios will never intersect.
fixes#25014
`implicitConv` tries to instantiate the supertype to convert to,
previously the bindings of `m` was shared with the bindings of the
converter but now an isolated match `convMatch` holds the bindings, so
`convMatch` is now used in the call to `implicitConv` instead of `m` so
that its bindings are used when instantiating the supertype.
fixes#25009
Introduced by #24176, when matching a set type to another, if the given
set is a constructor and the element types match worse than a generic
match (which includes the case with no match), the match is always set
to a convertible match, without checking that it is at least a
convertible match. This is fixed by checking this.
fixes#25000
A failed match on `nfDotField` tries to assert that the name of the dot
field is an identifier node. I am not exactly sure how but at some point
typed generics causes an `nfDotField` call to contain a symchoice for
the field name. The compiler does not use the fact that the field name
is an identifier, so the assert is loosened to allow any identifier-like
node kind. Could also investigate why the symchoice gets created, my
guess is that typed generics detects that the match fails but still
sends it through generic prechecking and doesn't remove the
`nfDotField`, which is harmless and it might cause more trouble to work
around it.
fixes#23713
`linkTo` normally sets the sym of the type as well as the type of the
sym, but this is not wanted for custom pragmas as it would look up the
definition of the generic param and not the definition of its value. I
don't see a practical use for this either.
fxies #24981
`m.g.graph.procGlobals` could change because the right side of `.global`
assignment (e.g. `let a {.global.} = g(T)`) may trigger injections for
unhandled procs
follows up #24871
For subscript assignments, if an overload of `[]=`/`{}=` is not found,
the LHS checks for overloads of `[]`/`{}` as a fallback, similar to what
field setters do since #24871. This is accomplished by just compiling
the LHS if the assignment overloads fail. This has the side effect that
the error messages are different now, instead of displaying the
overloads of `[]=`/`{}=` that did not match, it will display the ones
for `[]`/`{}` instead. This could be fixed by checking for `efLValue`
when giving the error messages for `[]`/`{}` but this is not done here.
The code for `[]` subscripts is a little different because of the
`mArrGet`/`mArrPut` overloads that always match. If the `mArrPut`
overload matches without a builtin subscript behavior for the LHS then
it calls `semAsgn` again with `mode = noOverloadedSubscript`. Before
this meant "fail to compile" but now it means "try to compile the LHS as
normal", in both cases the overloads of `[]=` are not considered again.

Collects `{.global.}` (i.e. if it was changed into a hook call: `=copy`,
`=sink`) in `injectDestructorCalls` and generates it in the init
sections in cgen
fixes#24947
When injectdestructors detects that a variable is a tuple unpacking temp
(i.e. it is an `skTemp`, is not a cursor, and has tuple type) it does
not generate a destructor for it and only generates sink/bit assignments
for its components. However the reason it does not generate a destructor
is that it expects it to be fully unpacked, this is true for unpackings
in for loops but not for tuple unpacking assignments which supports `_`
since #22537. Tuple unpacking definitions for `var`/`let`/`const` do not
generate `skTemp` and use the same symbol kind as the definition so they
did not have this problem.
To keep this compatible, the `_` parts of the tuple unpacking
assignments are now not ignored and unpacked into `let _ = ...`, which
generates its own destructor. Another option might be to use `skLet`
instead of `skTemp` but this might cause changes to behavior like
additional copies, I am not sure about this though.
todo: We can also give a deprecation message for `ltPtr`/`lePtr`
matching for cstring in `magicsAfterOverloadResolution`
follow up https://github.com/nim-lang/Nim/pull/24942
In `semExprWithType`: `if result.typ.kind in {tyVar, tyLent}: result =
newDeref(result)` derefed `var`/`lent`. Since it is not done for `sink`,
we need to skip `tySink` in the corresponding procs
Fixes#24895
- Remove all bio handling
- Remove all `sendPendingSslData` which only seems to make things work
by chance
- Wrap the client socket on `acceptAddr` (std/net does this)
- Do the SSL handshake on accept (std/net does this)
The only concern is if addWrite/addRead works well on Windows.
