(cherry picked from commit d15f63a0f2)
* change SysLockType_Reentrant
fix edge case where using SysLockType_Reentrant doesn't trigger an #include pthread.h
* syslocktype_reentrant now a var
* remove nodecl to remove empty system_syslocks.c
* let is better than var.
in reality SysLockType = enum, maybe that would be a better fix
* nimStackTraceOverride: enable stack traces in exceptions
This is a two-step stack trace collection scheme, because re-raised
exceptions will collect multiple stack traces but use them rarely, when
printing info about an uncaught exception, so it makes sense to only do
the cheap stack unwinding all the time and the relatively expensive
debugging information collection on-demand.
`asyncfutures` implements its own `$` proc for printing
`seq[StackTraceEntry]`, so we have to add the debugging info there, just
like we do for the private `$` proc in `system/excpt`.

* Changes for FreeRTOS/LwIP Port for the ESP32 (ESP-IDF)
Adding FreeRTOS/LwIP to compiler:
* adding freertos option
* dyncalls for freertos
* add freertos to posix os list
* adding lwip option
Setting up networking FreeRTOS/LwIP Port:
* setting up lwip network for freertos
* fixing posix / networking for freertos
* disable setInheritable for freerots
* using lwip for net control items
* Fix builds by ignoring lib/posix/posix_freertos_consts.nim similar to lib/posix/posix_other_consts.nim
* gc_regions: withRegion nows return the modified MemRegion
* gc_regions: make withScratchRegion dealloc correctly
* tests/gc: add tregionleak test
This test checks if memory within regions are freed properly.
* readLine: Unicode support for Windows console
When input is read from the Windows console, input encoding is UTF16. This is translated internally to UTF8.
* readLine: Remove recursive imports
* readLine: Fix issues with --gc:arc
**--gc:arc** defines **nimv2**. This changes the definition of **WideCStringObj**.
Also an empty string should be returned in case of EOF.
