Remove duktape and use QuickJS

[wargio]

@trufae this adds support to r2dec to use quickjs
unfortunately i couldn't use the code you implemented because i wanted to also support the ci.
i had to remove the Makefile version.

[trufae]

Cool! happy to see the relative paths. But i can't get it to compile:

With make

0$ make -C p
/Applications/Xcode.app/Contents/Developer/usr/bin/make build
make[1]: *** No rule to make target `duktape/duktape.o', needed by `core_pdd.dylib'.  Stop.
make: *** [all] Error 2
2$

and i assume you will deprecate the makefile :? and abandon the p directory where the duktape code was, so this is a leftover i guess.

With meson/ninja

0$ ninja -C b
ninja: Entering directory `b'
[13/18] Generating js/bytecode.h with a custom command

/Users/pancake/prg/r2js/b/subprojects/libquickjs/qjsc ../js/r2dec-plugin.js -m -N main_bytecode -c -o js/bytecode.h
Could not load '-m'
ninja: build stopped: subcommand failed.

the fix is this:

after this i managed to get it working, at least with small functions. otherwise i get an error (which maybe affects master, didnt tried)
a.zip <-

another thing i noticed is this CC error:

[0x100003a84]> pddi
ERROR: Missing space after CC
Do you want to print 1 lines? (y/N)

Do you have some numbers about the performance? hope the whole codebase gets some es6 improvements after merging this

[wargio]

i haven't tested time differences.

[trufae]

So it is ready for testing then? i can make up some numbers

[wargio]

looks like there are some issues on windows (tests) but for me can be tested

[wargio]

i need to still apply your changes

[wargio]

I have fixed windows build and the issue you had. i cannot tho fix the debian package or the macos one

[trufae]

I did some tests: r2 -q -c af -c '?t pdd' /bin/ls

• master branch: 0.59s
• qjs branch: 0.38s

building with meson b --buildtype=release

is there a way to install the plugin in the home? because ninja -C b install is putting things in the system path always

just do --prefix=whatever

[trufae]

yeah thing is that home directory doesnt follow system structure, but thats not really a blocker for me, so im good to get this merged. i have a bunch of other improvements but i would prefer to get this merged before moving forward.

Good work!
