* .forbids pragma: defining illegal effects for proc types
This patch intends to define the opposite of the .tags pragma: a way to define effects which are not allowed in a proc.
* updated documentation and changelogs for the forbids pragma
* renamed notTagEffects to forbiddenEffects
* corrected issues of forbids pragma
the forbids pragma didn't handle simple restrictions properly and it also had issues with subtyping
* removed incorrect character from changelog
* added test to cover the interaction of methods and the forbids pragma
* covering the interaction of the tags and forbids pragmas
* updated manual about the forbids pragma
* removed useless statement
* corrected the subtyping of proc types using the forbids pragma
* updated manual for the forbids pragma
* updated documentations for forbids pragma
* updated nim docs
* updated docs with rsttester.nim
* regenerated documentation
* updated rst docs
* Update changelog.md

* Change `styleCheck` to ignore foreign packages
* Symbols from foreign packages are now ignored.
* Fixed `styleCheck` violations in `compiler` package.
* Added symbol ownership to custom annotation pragmas.
* Minor refactors to cleanup style check callsites.
* Minor internal documentation of reasons why a symbol isn't checked.
Style violations were fixed in the compiler after thet were exposed by
the changes. The compiler wouldn't compile otherwise.
Symbol ownership for custom pragma annotations is needed for checking
the annotation's style. A NPE was raised otherwise.
Fixes#10201

* Fix a misunderstanding about excluding field style checks
I had refactored the callsites of `styleCheckUse` to apply the DRY
principle, but I misunderstood the field access handling in a template
as a general case. This corrects it.
* Fix some `styleCheck` violations in `compiler/evalffi`
The violations were exposed in CI when the compiler was built with
libffi.
* Removed some uneeded transitionary code
* Add changelog entry

* move io out of system
* fix tests
* fix tests
* next step
* rename to syncio
* rename
* fix nimscript
* comma
* fix
* fix parts of errors
* good for now
* fix test
* Use openarray of bytes in md5
* fix CI
* cleanup
* use noSideEffect for bootstrapping
* fix CI again
* actually fix CI by checking if it works
* this is getting ridiculous
* put old md5 version in compiler, remove vmop
* compiler/vmhooks: add getVar to allow vmops with var params
* addFloat vmops with var param
* cgen now renders float32 literals in c backend using roundtrip float to string
* CIs: attempt to use csources_v1
* also updated the BSDs
* also updated azure pipelines
* std modules should not itself use the 'std/' import dir...
* compiler has to be careful with std/ for v1 booting
* refactoring: idents don't need inheritance
* refactoring: adding an IdGenerator (part 1)
* refactoring: adding an IdGenerator (part 2)
* refactoring: adding an IdGenerator (part 3)
* refactoring: adding an IdGenerator (part 4)
* refactoring: adding an IdGenerator (part 5)
* refactoring: adding an IdGenerator (part 5)
* IdGenerator must be a ref type; hello world works again
* make bootstrapping work again
* progress: add back the 'exactReplica' ideas
* added back the missing exactReplica hacks
* make tcompilerapi work again
* make important packages green
* attempt to fix the build for 32 bit machines (probably need a better solution here)
* implements https://github.com/nim-lang/RFCs/issues/258
* don't be too strict with custom pragma blocks
* cast pragmas: documentation
* added most missing inference query procs to effecttraits.nim
* `nim doc --backend:js|cpp...`
`nim doc --doccmd:'-d:foo --threads:on'`
`nim r --backend:cpp...` (implies --run --usenimcache)
* --usenimcache works with all targets
* --docCmd:skip now skips compiling snippets; 50X speedup for doc/manual.rst
* Implement compileSetting() and compileSettingSeq()
* Change from magic to vmop
* better design for querySetting

* hashes: implement murmur3
* refactoring; there is only one murmurHash and it works at compile-time via VM hooks
* fixes JS tests
* makes toOpenArrayByte work with C++
* make it bootstrap in C++ mode for 0.20
This plugin provides essential building block for implementing incremental computations in your programs. The idea behind incremental computations is that if you do the same calculation multiple times but with slightly different inputs you don't have to recompute everything from scratch. Also you don't want to adopt special algorithms either, you would like to write your code in standard from scratch manner and get incrementality for free when it is possible.
The plugin computes the digest of the proc bodies, recursively hashing all called procs as well . Such digest with the digest of the argument values gives a good "name" for the result. Terminology loosely follows paper "Incremental Computation with Names" link below. It works well if you have no side effects in your computations. If you have global state in your computations then you will need problem specific workarounds to represent global state in set of "names" . SideEffect tracking in Nim also useful in this topic.
Classical examples:
Dashboard with ticking data. New data arrives non stop and you would like to update the dashboard recomputing only changed outputs.
Excel spreadsheet where user changes one cell and you would like to recompute all cells that are affected by the change, but do not want to recompute every cell in the spreadsheet.
