Newer emulator versions fail to create an AVD correctly.
Use an old Android emulator until we figure out why.

fix wrong definitions of getpwent_r and getgrent_r on solarish os
Closes#2908
* [man page for `getpwent_r`](https://illumos.org/man/3C/getpwnam)
* [man page for `getgrent_r`](https://illumos.org/man/3C/getgrnam)
You may find the definitions for `getpwnam_r/getpwuid_r/getgrnam_r/getgruid_r` exposed by `libc` are also wrong:
```c
struct passwd *getpwnam_r(const char *name, struct passwd *pwd,
char *buffer, int buflen);
```
```rust
pub fn getpwnam_r(
name: *const ::c_char,
pwd: *mut passwd,
buf: *mut ::c_cha
buflen: ::size_t,
result: *mut *mut passwd,
) -> ::c_int;
```
But actually they are **correct** as there are the POSIX-conforming definitions (see `Standard conforming` section of above man pages):
```
Standard conforming
cc [ flag...] file... -D_POSIX_PTHREAD_SEMANTICS [ library... ]
int getpwnam_r(const char *name, struct passwd *pwd, char *buffer,
size_t bufsize, struct passwd **result);
int getpwuid_r(uid_t uid, struct passwd *pwd, char *buffer,
size_t bufsize, struct passwd **result);
```
`getpwent_r/getgrent_r` don't get lucky, they do not have the POSIX-conforming alternatives.
To double check this, I searched its [source code](https://github.com/illumos/illumos-gate/blob/master/usr/src/lib/libc/port/gen/getpwnam_r.c):
```shell
$ rg "__posix_getpwnam_r"
port/mapfile-vers
1582: __posix_getpwnam_r;
port/gen/getpwnam_r.c
152:__posix_getpwnam_r(const char *name, struct passwd *pwd, char *buffer,
$ rg "__posix_getpwent_r"
$
```
Enforce order of any `s_*!` macro calls
Before this change, only the order of `s!` was checked. After, it also checks `s_no_extra_traits!` and `s_paren!`. Only the order is checked, not the number of calls. This is required because multiple calls have to be allowed.

linux: Add POSIX_SPAWN_SETSID flag
This flag allows the child process created by POSIX spawn to create a new session and become leader of a new process group. Expose the flag so that Rust code can use it.

add dirname and basename
This PR adds `dirname(3)` and `basename(3)` on the following platforms:
* Linux with glibc
* Linux with musl
* Android
* FreeBSD
* DragonFlyBSD
* NetBSD
* OpenBSD
* Apple platforms
I tested this PR on my host machine (Linux with glibc), and got the following error:
```

error: test failed, to rerun pass '--test main'
```
The reason for this error probably is that there are two `basename(3)` on Linux with glibc, the POSIX version and the GNU version, and they clash with each other. In C, if one `#include <libgen.h>`, then the POSIX version will be available; If one ` #define _GNU_SOURCE` and `#include <string.h>`, then the GNU one will be used.
Can we distinguish them in `libc`?
