Fix Windows 7 support (#19) This change pays off technical debt with the function -> DLL mappings in libc/nt/master.sh, which was originally defined based on binary analysis on Windows 10. It's now been updated so the kernel32/kernelbase/advapi32 imports should be exactly as they are written, on the MSDN documentation and that wouldn't have been easy without Geoff Chappell's work thank him https://www.geoffchappell.com/studies/windows/win32/index.htm

Fold conv package into fmt Both packages had nearly identical dependency requirements, so merging them should help reduce the complexity of the build graph.

LIBC_STR \
Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Delete ASAN It hasn't been helpful enough to be justify the maintenance burden. What actually does help is mprotect(), kprintf(), --ftrace and --strace which can always be counted upon to work correctly. We aren't losing much with this change. Support for ASAN on AARCH64 was never implemented. Applying ASAN to the core libc runtimes was disabled many months ago. If there is some way to have an ASAN runtime for user programs that is less invasive we can potentially consider reintroducing support. But now is premature.

Add cpu / mem / fsz limits to build system Thanks to all the refactorings we now have the ability to enforce reasonable limitations on the amount of resources any individual compile or test can consume. Those limits are currently: - `-C 8` seconds of 3.1ghz CPU time - `-M 256mebibytes` of virtual memory - `-F 100megabyte` limit on file size Only one file currently needs to exceed these limits: o/$(MODE)/third_party/python/Objects/unicodeobject.o: \ QUOTA += -C16 # overrides cpu limit to 16 seconds This change introduces a new sizetol() function to LIBC_FMT for parsing byte or bit size strings with Si unit suffixes. Functions like atoi() have been rewritten too.
