* nimRawSetjmp: support Windows
Using `_setjmp()` directly is required to avoid some rare (but very
annoying) exception-related stack corruption leading to segfaults on
Windows, with Mingw-w64 and SEH.
More details: https://github.com/status-im/nimbus-eth2/issues/3121
Also add "nimBuiltinSetjmp" - mostly for benchmarking.

* fixes a possible 'javascript:' protocol exploit [backport:1.0]
* add tests
* Update tests/stdlib/trstgen.nim

* Fix#19052; [backport:1.6.0]
Adds a compile flag to avoid a getrandom syscall, fixing #19052.
This is neccesary when the getrandom syscall is missing, as noted in #19052, particularly in kernel versions < 3.17 when getrandom was introduced. Specifically relevant is this is missing from kernel 3.10, which is the supported kernel throughout RHEL 7 and CentOS 7, which is widely used at many organizations. Without this, versions of nim that include sysrand (i.e. versions >= 1.6.0) will not compile without modification, however with this change a compile flag may be used to fall back using /dev/urandom as done with any unknown Posix OS (preferred here as a fallback since it already supplies a cryptographically secure PRNG and existing code deals with entropy pool init, etc).
The change is placed behind a compile flag, as discussed in github ticket #19052 (summed up here):
* First, I can't seem to catch that a importc such as SYS_getrandom is declared without using it (the declared proc returns true, but compiler throws an undeclared identifier flag when referencing it).
* Second, it seemed preferable to be behaviorally explicit vs implicit when considering this is intended to be a cryptographically secure PRNG.
* Third, if I intend to compile on a kernel >= 3.17 while running the binary on at least one system < 3.17, I'll want to be able to target this without relying on a compile time determination if the getrandom syscall is available.
* Documenting compile flag for -d:nimNoGetRandom and adding changelog entry
Related to #19052 and comments in PR #19053. Also created a new changelog file since none currently exists.

(cherry picked from commit dde556665a)
Nim 1.4.x compiled the below code without error when using
`--experimental:strictFuncs`
import std/sequtils
type Foo = ref object
let foo1 = Foo()
let foo2 = Foo()
let foos = @[foo1, foo2]
let fooTuples = @[(foo1, 1), (foo2, 2)]
discard repeat(foo1, 3)
discard zip(foos, foos)
discard unzip(fooTuples)
However, since 2020-12-09, devel Nim produced errors like
/tmp/bar.nim(11, 15) template/generic instantiation of `repeat` from here
/foo/nim/pure/collections/sequtils.nim(172, 6) Error: 'repeat' can have side effects
an object reachable from 'x' is potentially mutated
/foo/nim/pure/collections/sequtils.nim(183, 15) the mutation is here
/foo/nim/pure/collections/sequtils.nim(183, 15) is the statement that connected the mutation to the parameter
This commit reverts some `proc` to `func` changes so that code that:
- calls `repeat`, `zip`, or `unzip`
- and instantiates them with types containing `ref`
can once again be compiled with `strictFuncs`. Otherwise, a user might
be forced to drop or alter their `strictFuncs` use when upgrading from
Nim 1.4.x, or when writing new code that uses these procedures (at least
for now, with the current `strictFuncs` implementation).
This commit also adds tests to assert that the remaining funcs in this
module can be compiled with `strictFuncs` when used with types
containing `ref`.
The original batch of `proc` to `func` changes in `sequtils.nim` was in
commit 6f57ebae34, which was partially reverted in 38eb021f81.

* Fixed `strictFuncs` support for `std/pegs`
Enabled `std/pegs` in the `strictFuncs` import test.
Fixes#18057Fixes#16892
See #18111
* Rebased from `devel`
* Conditionally compile `std/pegs` in `koch`
This is for supporting `csources` bootstrap.
