c4947c8879 Use secure random generator on macOS
The implementation of arc4random_buf differs from its documentation. It
is documented as "always successful, and no return value is reserved to
indicate an error" for the sake of FreeBSD compatibility [1]. However,
the actual implementation on macOS invokes function "ccrng_generate" [2]
without validating the error cases. It might fail silently[3], which leads
to unexpected source of entropy.

The original arc4random used the RC4 a.k.a. ARC4 algorithm, and ChaCha20
based implementation was introduced in FreeBSD 12.0. Since macOS 10.12,
it was replaced with the NIST-approved AES cipher, and it may be replaced
again in the future as cryptographic techniques advance. Therefore, we
should not assume that arc4random never fails.

On the contrary, CCRandomGenerateBytes(), part of Cryptographic Services [4],
returns cryptographically strong random bits with explicit status code.
This patch properly calls CCRandomGenerateBytes() and checks the status.

d48c93af2c Add branch hint for _mi_os_good_alloc_size
In _mi_os_good_alloc_size, overflow caused by alignment size is rare,
and this patch added the appropriate branch hint during range checks.

0f57425f80 Distinguish SI and Binary Prefixes
SI prefixes [the decimal prefixes] refer strictly to powers of 10. They
should not be used to indicate powers of 2. e.g., one kilobit
represents 1000 bits instead of 1024 bits. IEC 60027‐2 symbols are
formed adding a "i" to the SI symbol (e.g. G + i = Gi).

3402c6cc3f Revise the use of macOS predefined macro
Quoted from "Porting UNIX/Linux Applications to OS X,"[1]
* macro __MACH__ is defined if Mach system calls are supported;
* macro __APPLE__ is defined in any Apple computer.

__MACH__ is not specific to macOS since GNU/Hurd runs on a Mach-based
microkernel (gnumach) [2]. __MACH__ is defined by the compiler,
leading to potential confusions. The solution is just changing the
checked identifier (i.e. __APPLE__), so it is really used only on
macOS.
