Fix an edge case by printing the required space when, the currency
symbol succeeds the value, a space separates the sign from the value and
the sign position precedes the quantity and the currency symbol.
In other words:
n_cs_precedes = 0

n_sign_posn = 1

Avoid an out-of-bounds access when trying to set the space_char using an
international currency format (%i) and the C/POSIX locale.
The current code tries to read the SPACE from int_curr_symbol[3]:
currency_symbol = strdup(lc->int_curr_symbol);
space_char = *(currency_symbol+3);
But on C/POSIX locales, int_curr_symbol is empty.
Three implementations have been examined: NetBSD[1], Darwin[2], and
Illumos[3]. Only NetBSD has fixed it[4].
Darwin and NetBSD also trim the mandatory final SPACE character after
reading it.
Locale Format Darwin/NetBSD FreeBSD/Illumos
en_US.UTF-8 [%i] [USD123.45] [USD 123.45]
fr_FR.UTF-8 [%i] [123,45 EUR] [123,45 EUR ]
This commit only fixes the out-of-bounds access.

Currently libvmmapi provides a way to get a list of the allowed ioctls
on the vmm device file, so that bhyve can limit rights on the device
file fd. The interface is rather strange: it allocates a copy of the
list but returns a const pointer, so the caller has to cast away the
const in order to free it without aggravating the compiler.
As far as I can see, there's no reason to make a copy of the array, but
changing vm_get_ioctls() to not do that would break compatibility. So
this change just introduces a better interface: move all rights-limiting
logic into libvmmapi.
Any new operations on the fd should be wrapped by libvmmapi, so also
discourage use of vm_get_device_fd(). Currently bhyve uses it only when
limiting rights on the device fd.
No functional change intended.

Otherwise we do not fall back to sysctls if the auxv entries are not
defined by the kernel. Arguably this is not a bug since we do not
support newer libc running on an older kernel, but we can be a bit more
gentle for the benefit of Valgrind or any other software which
synthesizes the auxv for virtualization purposes.

kib@ pointed out that it is perfectly fine to write at arbitrary regular
file offsets. For example, in a 4K block size character device, geom
doesn't support writing / reading 515 byte blocks. The description is
perhaps not applicable to all EINVALs returned.
The read system call will return EINVAL if the current file offset is
not a multiple of the block size. This also applies to write(2). Add an
entry for EINVAL about this error to both man pages.

DevPathToTextUsbWWID allocates a separate copy of the SerialNumber
string to append a null terminator if the original string is not
