812f28b79c BoringSSL: Allow internal AES key wrap to be used with "OpenSSL" build
It looks like BoringSSL has removed the AES_wrap_key(), AES_unwrap_key()
API. This broke wpa_supplicant/hostapd build since those functions from
OpenSSL were used to replace the internal AES key wrap implementation.
Add a new build configuration option
(CONFIG_OPENSSL_INTERNAL_AES_WRAP=y) to allow the internal
implementation to be used with CONFIG_OPENSSL=y build to allow build
against the latest BoringSSL version.

7cb53ded11 Add build option to remove all internal RC4 uses
The new CONFIG_NO_RC4=y build option can be used to remove all internal
hostapd and wpa_supplicant uses of RC4. It should be noted that external
uses (e.g., within a TLS library) do not get disabled when doing this.

This removes capability of supporting WPA/TKIP, dynamic WEP keys with
IEEE 802.1X, WEP shared key authentication, and MSCHAPv2 password
changes.

276a3c44dd OpenSSL: Implement aes_wrap/aes_unwrap through EVP for CONFIG_FIPS=y
The OpenSSL internal AES_wrap_key() and AES_unwrap_key() functions are
unfortunately not available in FIPS mode. Trying to use them results in
"aes_misc.c(83): OpenSSL internal error, assertion failed: Low level API
call to cipher AES forbidden in FIPS mode!" and process termination.
Work around this by reverting commit
f19c907822 ('OpenSSL: Implement aes_wrap()
and aes_unwrap()') changes for CONFIG_FIPS=y case. In practice, this
ends up using the internal AES key wrap/unwrap implementation through
the OpenSSL EVP API which is available in FIPS mode. When CONFIG_FIPS=y
is not used, the OpenSSL AES_wrap_key()/AES_unwrap_key() API continues
to be used to minimize code size.

f0356ec85c eloop: Add epoll option for better performance
This patch adds epoll option for the eloop implementation. This can be
selected with the CONFIG_ELOOP_EPOLL=y build option.

[merit]
See Table1.

Table1. comparison table
+--------+--------+-----------+------------+-------------+
|        | add fd | remove fd | prepare fd | dispatch fd |
+--------+--------+-----------+------------+-------------+
| select | O(1)   | O(1)      | O(N)       | O(N)        |
+--------+--------+-----------+------------+-------------+
| poll   | O(1)   | O(1)      | O(N)       | O(N)        |
+--------+--------+-----------+------------+-------------+
| epoll  | O(1)   | O(1)      | 0          | O(M)        |
+--------+--------+-----------+------------+-------------+
"add fd" is addition of fd by eloop_sock_table_add_sock().
"remove fd" is removal of fd by eloop_sock_table_remove_sock().
"prepare fd" is preparation of fds before wait in eloop_run().
"dispatch fd" is dispatchment of fds by eloop_sock_table_dispatch().
"N" is all watching fds.
"M" is fds which could be dispatched after waiting.

As shown in Table1, epoll option has better performance on "prepare fd" column.
Because select/poll option requires setting fds before every select()/poll().
But epoll_wait() doesn't need it.

And epoll option has also better performance on "dispatch fd" column.
Because select/poll option needs to check all registered fds to find out
dispatchable fds. But epoll option doesn't require checking all registered fds.
Because epoll_wait() returns dispatchable fd set.

So epoll option is effective for GO/AP functionality.

[demerit]
The epoll option requires additional heap memory. In case of P2P GO, it is
about 8K bytes.

(link local, which is based on the MAC address). Also add scope id
support for link local case.
