Fix errno conflict

Newlib defines errno as

#define errno (*errno())

In case this is expanded in a function parameter, e.g.

void f(int errno) { ... }

then we have a function pointer parameter instead of the integer scalar.

Property mode set to 100644

125	* struct inpcb captures the network layer state for TCP, UDP, and raw IPv4
126	* and IPv6 sockets. In the case of TCP, further per-connection state is
127	* hung off of inp_ppcb most of the time. Almost all fields of struct inpcb
128	* are static after creation or protected by a per-inpcb rwlock, inp_lock. A
129	* few fields also require the global pcbinfo lock for the inpcb to be held,
130	* when modified, such as the global connection lists and hashes, as well as
131	* binding information (which affects which hash a connection is on). This
132	* model means that connections can be looked up without holding the
133	* per-connection lock, which is important for performance when attempting to
134	* find the connection for a packet given its IP and port tuple. Writing to
135	* these fields that write locks be held on both the inpcb and global locks.
136	*
137	* Key:
138	* (c) - Constant after initialization
139	* (i) - Protected by the inpcb lock
140	* (p) - Protected by the pcbinfo lock for the inpcb
141	* (s) - Protected by another subsystem's locks
142	* (x) - Undefined locking
143	*
144	* A few other notes:
145	*
146	* When a read lock is held, stability of the field is guaranteed; to write
147	* to a field, a write lock must generally be held.
148	*
149	* netinet/netinet6-layer code should not assume that the inp_socket pointer
150	* is safe to dereference without inp_lock being held, even for protocols
151	* other than TCP (where the inpcb persists during TIMEWAIT even after the
152	* socket has been freed), or there may be close(2)-related races.
153	*
154	* The inp_vflag field is overloaded, and would otherwise ideally be (c).
