daf39c03bd dns_client: directly initialize g_dns_servers and remove dns_initialize directly
g_dns_servers need init before dns_query, Otherwise sim can not add default
dns server when use usrsock mode to share host network.

Avoid similar problems in the future, so directly initialize g_dns_servers.

2ce12617a1 libs: spawn: Add forkaround for posix_spawn_file_actions_adddup2()
Summary:
- I noticed that adb shell failed when sh is spawned.
- Finally, I found that an error happened when executing dup2() action
  if the file descriptor has the O_CLOEXEC option.
- This commit fixes this issue by dropping the option in the API.

Impact:
- posix_spawn_file_actions_adddup2() only

Testing:
- adbd with sabre-6quad:netnsh (will be merged later)

bf91047f33 libc: Fix getrandom() bug: Didn't propagate read error
* libs/libc/misc/lib_getrandom.c, in function getrandom():
  We were assigning the return value of _NX_READ() to nbytes, a
  variable of the unsigned type size_t. Note that _NX_READ() resolves
  to either read() or nx_read(), both of which return the signed type
  ssize_t to indicate either the number of bytes read successfully
  (>= 0) or an error (< 0). Then we were testing for a negative
  size_t value, a condition that can never occur. The end result is
  that if an error occured in _NX_READ(), it would never be detected
  and getrandom() would return some large positive value. This bug is
  corrected by assigning the return value of _NX_READ() to a new local
  variable, ret, of size ssize_t.
