Make some systemic improvements
- add vdso dump utility - tests now log stack usage - rename g_ftrace to __ftrace - make internal spinlocks go faster - add conformant c11 atomics library - function tracing now logs stack usage - make function call tracing thread safe - add -X unsecure (no ssl) mode to redbean - munmap() has more consistent behavior now - pacify fsync() calls on python unit tests - make --strace flag work better in redbean - start minimizing and documenting compiler flags

Makes directories.

Unlike mkdir() this convenience wrapper will automatically create
|
||||
parent parent directories as needed. If the directory already exists
|
||||
then, unlike mkdir() which returns EEXIST, the makedirs() function
|
||||
will return success.
|
||||
|
||||
`path` is the path of the directory you wish to create.
|
||||
|
||||
`mode` is octal permission bits, e.g. `0755`.
