Do not call wtap_file_read_unknown_bytes() or
wtap_file_read_expected_bytes() from an open routine - open routines are
supposed to return -1 on error, 0 if the file doesn't appear to be a
file of the specified type, or 1 if the file does appear to be a file of
the specified type, but those macros will cause the caller to return
FALSE on errors (so that, even if there's an I/O error, it reports "the
file isn't a file of the specified type" rather than "we got an error
trying to read the file").
When doing reads in an open routine before we've concluded that the file
is probably of the right type, return 0, rather than -1, if we get
WTAP_ERR_SHORT_READ - if we don't have enough data to check whether a
file is of a given type, we should keep trying other types, not give up.
For reads done *after* we've concluded the file is probably of the right
type, if a read doesn't return the number of bytes we asked for, but
returns an error of 0, return WTAP_ERR_SHORT_READ - the file is
apparently cut short.
For NetMon and NetXRay/Windows Sniffer files, use a #define for the
magic number size, and use that for both magic numbers.

Allow bigger snapshot lengths for D-Bus captures.
Use WTAP_MAX_PACKET_SIZE_STANDARD, set to 256KB, for everything except
for D-Bus captures. Use WTAP_MAX_PACKET_SIZE_DBUS, set to 128MB, for
them, because that's the largest possible D-Bus message size. See
https://bugs.freedesktop.org/show_bug.cgi?id=100220
for an example of the problems caused by limiting the snapshot length to
256KB for D-Bus.
Have a snapshot length of 0 in a capture_file structure mean "there is
no snapshot length for the file"; we don't need the has_snap field in
that case, a value of 0 mean "no, we don't have a snapshot length".
In dumpcap, start out with a pipe buffer size of 2KB, and grow it as
necessary. When checking for a too-big packet from a pipe, check
against the appropriate maximum - 128MB for DLT_DBUS, 256KB for
everything else.

Set more fields when writing out Commview Wi-Fi files.

Add some higher-level file-read APIs and use them.
Add wtap_read_bytes(), which takes a FILE_T, a pointer, a byte count, an
error number pointer, and an error string pointer as arguments, and that
treats a short read of any sort, including a read that returns 0 bytes,
as a WTAP_ERR_SHORT_READ error, and that returns the error number and
string through its last two arguments.
Add wtap_read_bytes_or_eof(), which is similar, but that treats a read
that returns 0 bytes as an EOF, supplying an error number of 0 as an EOF
indication.
Use those in file readers; that simplifies the code and makes it less
likely that somebody will fail to supply the error number and error
string on a file read error.

Clean up 802.11 radio information handling.
Have a field that holds the PHY type but nothing else. Have
a union with structures holding PHY-type-specific information, as a
bunch of attributes are PHY-specific.
If we have a channel and band, but don't have the frequency, attempt to
calculate the frequency, and add that to the radio information if we
succeed. If we have the frequency, but don't have the channel, attempt
to calculate the channel, and add that to the radio information if we
succeed.
Handle FHSS information, 11a "half/quarter-clocked" and turbo
information, 11g normal vs. Super G, additional 11n and 11ac
information, and the "short preamble" flag for 11b and 11g.
Add a PHY type for 11 legacy DSSS and detect it if possible.
Clean up the AVS dissector - make all fields wlancap. fields (if you
want generic fields, use the wlan_radio. fields).
Set more fields when writing out Commview Wi-Fi files.
