9838b7032e Introduce a consistent coding style
This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:

	-bap
	-psl
	-T PrivatePtr
	-T pmWait
	-T _XFUNCPROTOBEGIN
	-T _XFUNCPROTOEND
	-T _X_EXPORT

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.

The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.

The comparison was done with this script:

dir1=$1
dir2=$2

for dir in $dir1 $dir2; do
	(cd $dir && find . -name '*.o' | while read file; do
		dir=`dirname $file`
		base=`basename $file .o`
		dump=$dir/$base.dump
		objdump -d $file > $dump
	done)
done

find $dir1 -name '*.dump' | while read dump; do
	otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
	diff -u $dump $otherdump
done

50b1097643 Constify the reason string throughout the authorization check framework
Almost all of the places the string is assigned point to a literal
string constant, so use const char * for those, and const char **
for function calls that return it via an argument.   Fortunately
the top level function, ClientAuthorized, which returns the string
as its return value is called from only one place, ProcEstablishConnection.

ProcEstablishConnection stores either that return value or a string literal
in char *reason.  It only uses reason as an argument to SendConnSetup.
SendConnSetup passes the reason argument to strlen & WriteToClient,
both of which already have const qualifiers on their args.
Thus added const to the reason variable in ProcEstablishConnection
and the reason argument to SendConnSetup.

Fixes gcc warnings:

9999819601 Constify string for authorization protocol names
gcc was warning from storing string constants in a char *name field:
auth.c:64:1: warning: initialization discards qualifiers from pointer target type
auth.c:72:1: warning: initialization discards qualifiers from pointer target type
auth.c:81:1: warning: initialization discards qualifiers from pointer target type

Making the field const requires changing AuthorizationFromID to take
a const char ** pointer for the name argument which it sets to point
to the matching name entry.

Changing that argument requires changing its sole caller in the security
extension to pass the address of a const char * variable to it, which it
can do, since the only thing it does with the returned name is to pass
it back to the RemoveAuthorization function that already expects a const
char *name.

b31d104fc0 os/log: Add LogVHdrMessageVerb and friends
LogVHdrMessageVerb allows a custom header to be inserted in a log message,
between the Log system's MessageType string, and a formatted variable
message body. The custom header can itself be a formatted variable string.

These functions can be used, for example, by driver abstraction layers to
format specific driver messages in a standard format, but do it in a way
that is efficient, obeys the log-layers verbosity settings, and is safe
to use in signal handlers (because they don't call malloc), even for
types besides X_NONE.

f51e42f583 Terminate the log with one last message.
Instead of just closing the log when everything is done, put one more
message in stating that we're actually terminating. Users or scripts that
look at the Xorg.log will then know that a) the server has terminated
properly and b) why the server terminated (to some degree, given that most
real-world errors will be caused by AbortServer()).

c95c1d338f Add asprintf() implementation for platforms without it
Provides a portable implementation of this common allocating sprintf()
API found in many, but not yet all, of the platforms we support.
If the platform provides vasprintf() we simply wrap it, otherwise we
implement it - either way callers can use it regardless of platform.

Since not all platforms guarantee to NULL out the return pointer on
failure, we don't either, and require callers to check the return
value for -1.

The old Xprintf() API is deprecated, but left for compatibility for now.

The new API is added in a new header so that it can be used in parts of
the server such as hw/xfree86/parser that don't include all the server
headers.

b1dac41fb3 Use libtool convenience libraries and better "symbol" table.
All .a libraries were converted to .la, and instead of linking the
Xorg binary with a mix of .a and .la, and adding some libraries more
then once in the command line, etc, now it generates a single libxorg.la
from all the required convenience libraries, and links with a dummy
xorg.c (that should usually be the file with the main function...).
This removes the requirement of some things like libosandcommon and
libinit, that existed to circumvent problems when linking multiple
.a and .la in the final Xorg binary.

  The "symbol table" is now generated dynamically, by a shell script,
with an embedded gawk parser that parses cpp output. The new file
sdksyms.sh is generated by hand by analyzing all Makefile.am's and
making it create a sdksyms.c file, that includes all sdk headers that
will add symbols for the Xorg binary. Module headers aren't read, and
a in 2 files it was required to add a "<hash>ifndef XorgLoader" around
declarations shared between the Xorg binary and libextmod. A few
other changes were added to other sdk headers, like preventing
multiple inclusion, or including other headers to satisfy dependencies.

  This should be a lot more portable, and better (hopefully properly)
using libtool to generate convenience libraries.

49f77fff14 Rework symbol visibility for easier maintenance
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.

  This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)

  LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.

  xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).

f01e149d1a Move SIGUSR1 notification as late as possible.
If we inherited a signal mask from the parent process that ignores SIGUSR1,
then we will send SIGUSR1 to the parent to indicate when we're ready to
accept connections.  Unfortunately, we send this notification way too
early, right after creating the sockets rather than just before entering
the main loop.

Move it to just before Dispatch() so we're not lying quite so much.
