41c40f4bbe Fix fork() on Linux/sparc64 
fork() on Linux/sparc64 seems to return its result in two registers,
with %o0 always holding the current process' PID, and the parent/child
status returned in %o1. Add some glue code to convert those into
the libc-style return value.

3e22077d46 Fix the ELF base calculation 
Find the effective ELF load address in dl_iterate_phdr by computing the
difference between the in-memory phdr and its p_vaddr specified in the
ELF file.

This makes the dl_iterate_phdr test pass and restores the stack traces.

Make it behave like the read() wrapper for unix systems.

0e95fa455c std: Split kernel&libc definitions of stat struct 
There's no guarantee for the kernel definition to be ABI compatible with
the libc one (and vice versa).
There's also no guarantee of ABI compatibility between musl/glibc.

Fun, isn't it?

Fix Darwin codepath 
On Darwin, according to the man pages for setrlimit(), when adjusting
max number of open fds, the reported hard max by getrlimit() is only
theoretical, while the actual maximum, set in the kernel, is hardcoded
in the header file. Therefore, the reported max has to be adjusted
as `min(OPEN_MAX, lim.max)`.

2dd8613adc "The Traveling Wilburys' - Handle With Care" 
Both `offset` and `len` are `off_t`.

Like the rest of the std lib we assume that `_FILE_OFFSET_BITS == 64`
is always true, so that `off_t` is a `u64`.

When passing to 32-bit kernels, we split these into two `u32`
parameters.
