matt335672 7fe5b3ea34 Move pause key processing from xorgxrdp
This commit moves processing of the pause key from xorgxrdp
back to xrdp itself, so that the key can be passed to the VNC
backend.

matt335672 ef14039c62 Use correct names for key events
Replace definitions in ms-rdpbcgr.h marked as TODO with the
names defined in [MS-RDPBCGR]

Some other simplifications around the fake Unicode event processing
have also been made.

matt335672 c91ef80ca9 Implement scancode indexing
The mapping from scancodes to the indexes used in xrdp_keymap
is not well designed and contains an implicit dependency on
keycode values.

This mapping is alse slightly different from the index used for
the 'keys' map in the xrdp_wm structure.

This commit introduces support for mapping scancodes directly
to 'scancode indexes' suitable for indexing into both structures.

Some renaming is also done; [MS-RDPBCGR] uses the terms scancode
and keyCode interchangeably. An effort is made to use key_code for a
raw value from a TS_KEYBOARD_EVENT, and scancode for a value which is
produced by the scancode module.

matt335672 0f6e731524 clipboard: Allow a file read to return 0 for EOF
When used with a FreeRDP client on Linux, a file copy operation from
the clipboard detects end-of-file by a read returning 0 bytes. This is
currently marked as an error.

It is assumed that mstsc.exe detects end-of-file in another way, which
is why this has not been found before.

matt335672 34b5582460 Remove unnecessary copy from clipboard_get_files()
The routine clipboard_get_files() parses a potentially long string,
and copies portions of it into a temporary buffer. This buffer is then
passed to clipboard_get_file() as pointer + length;

The buffer is inadequately sized for very long filenames which may
approach XFS_MAXFILENAMELEN in length. This can cause chansrv to fail
when the user copies such filenames.

It turns out the buffer is unnecessary, as the filenames can be
passed directly into clipboard_get_file() from the source string,
using pointer + length. This avoids the length limitation entirely.

matt335672 a90228241d Remove hard-coded filename limit for clipboard file lists
The limit of 256 characters for clipboard files is limiting for
many Asian locales, particularly as '%xx' notation is used to
communicate bytes with bit 7 set.

matt335672 d8b5435710 Dynamically allocate XFS filesystem names
Replace the 256 byte buffer used for names in the XFS filesystem with a
dynamically allocated buffer.

The define XFS_MAXFILENAMELEN which used to be 255 has been retained,
but bumped to 1023. This value is no longer used for long-lived
allocations, but is used in chansrv_fuse.c for maintaining state
information for in-fligh I/O requests.

matt335672 c9e84dc16c Fix potential name buffer overflows in redirector
The state buffers used by the following structs in chansrv_fuse.c
are one byte too small for filenames of length XFS_MAXFILENAMELEN:-
- struct state_lookup
- struct state_create
- struct state_rename

In practice, there is no runtime danger, as XFS_MAXFILENAMELEN is 255,
and these buffers will be followed by non-byte aligned data. Nevertheless
this should be fixed to prevent problems if the value is changed.

matt335672 a4f57572e6 sesman: Copy IP address to pre_session_item struct
struct pre_session_item has an entry for the start_ip_addr which is not
being filled in. This is not normally needed, as the IP address of the
session is passed into the session another way, but it is needed if the
session selection Policy contains the 'I' selector.

matt335672 ce355fc235 Allow for xrdp not being able to delete PID file
If xrdp is running with dropped privileges it won't be able to delete
the PID file it's created. Places where xrdp is stopped need to cater
for this.

It's prefereable to do this than make the PID file writeable by xrdp
with dropped privileges, as this can still lead to DoS attacks if an
attacker manages to modify the PID file from a compromised xrdp
process.

matt335672 ddff9ebb32 Refactor xrdp_listen to allow for privilege drop
- xrdp_listen.c is refactored so we can create the
  listening socket(s) before dropping privileges.
- The code which reads startup params from xrdp.ini
  is moved from xrdp_listen.c to xrdp.c, so it
  is only called once if we test the listen before
  starting the daemon.

(as when one would run "setxkbmap dvorak"); one must now use either
"us dvorak" or "us(dvorak)"
