Fix link order in cosmopolitan.a It turned out that the linker was doing the wrong with the amalgamation library concerning weak stubs. A regression test has been added and new binaries have been uploaded to https://justine.lol/cosmopolitan/ Ideally this should be fixed by building a tool that turns multiple .a files into a single .a file with deduplication. As a workaround for now the cosmopolitan.a build is restructured to not include LIBC_STUBS which meant technical debt needed to be paid off where non-stub interfaces were moved to LIBC_INTRIN and LIBC_NEXGEN32E. Thank @PerfectProductions in #31 for the report!

Improve memory safety This commit makes numerous refinements to cosmopolitan memory handling. The default stack size has been reduced from 2mb to 128kb. A new macro is now provided so you can easily reconfigure the stack size to be any value you want. Work around the breaking change by adding to your main: STATIC_STACK_SIZE(0x00200000); // 2mb stack If you're not sure how much stack you need, then you can use: STATIC_YOINK("stack_usage_logging"); After which you can `sort -nr o/$MODE/stack.log`. Based on the unit test suite, nothing in the Cosmopolitan repository (except for Python) needs a stack size greater than 30kb. There are also new macros for detecting the size and address of the stack at runtime, e.g. GetStackAddr(). We also now support sigaltstack() so if you want to see nice looking crash reports whenever a stack overflow happens, you can put this in main(): ShowCrashReports(); Under `make MODE=dbg` and `make MODE=asan` the unit testing framework will now automatically print backtraces of memory allocations when things like memory leaks happen. Bugs are now fixed in ASAN global variable overrun detection. The memtrack and asan runtimes also handle edge cases now. The new tools helped to identify a few memory leaks, which are fixed by this change. This change should fix an issue reported in #288 with ARG_MAX limits. Fixing this doubled the performance of MKDEPS.COM and AR.COM yet again.
