47e06c6d4e Reorganize the source tree.
* Documentation is now in "docs".
 * Source code is now in "src".
 * Misc. fixes here and there so that everything still works.

I think I got everything in this commit, but I only tested this
on Linux (Make) and Windows (CMake), so I might've messed
something up on other platforms...

80322adaa0 redo of the -dD option
functionality was broken some time ago and was removed
    by the "tccpp: fix issues, add tests"

    fix: LINE_MACRO_OUTPUT_FORMAT_NONE in pp_line()
    means: output '\n' and not "don't output at all"

a98fd13090 a mem leak fix for "ability to compile multiple *.c files with -c switch"
A new version of the MEM_DEBUG will be submitted next. This version is
    not depend on the malloc_usable_size() presense in the libc and
    print a places where a leaked chunks of memory was allocated.

30df3189b1 tccpp: fix issues, add tests
* fix some macro expansion issues
* add some pp tests in tests/pp
* improved tcc -E output for better diff'ability
* remove -dD feature (quirky code, exotic feature,
  didn't work well)

Based partially on ideas / researches from PipCet

Some issues remain with VA_ARGS macros (if used in a
rather tricky way).

Also, to keep it simple, the pp doesn't automtically
add any extra spaces to separate tokens which otherwise
would form wrong tokens if re-read from tcc -E output
(such as '+' '=')  GCC does that, other compilers don't.

 * cleanups
  - #line 01 "file" / # 01 "file" processing
  - #pragma comment(lib,"foo")
  - tcc -E: forward some pragmas to output (pack, comment(lib))
  - fix macro parameter list parsing mess from
    a3fc543459
    a715d7143d
    (some coffee might help, next time ;)
  - introduce TOK_PPSTR - to have character constants as
    written in the file (similar to TOK_PPNUM)
  - allow '\' appear in macros
  - new functions begin/end_macro to:
      - fix switching macro levels during expansion
      - allow unget_tok to unget more than one tok
  - slight speedup by using bitflags in isidnum_table

Also:
  - x86_64.c : fix decl after statements
  - i386-gen,c : fix a vstack leak with VLA on windows
  - configure/Makefile : build on windows (MSYS) was broken
  - tcc_warning: fflush stderr to keep output order (win32)

a13f183e4c ability to compile multiple *.c files with -c switch

0536407204 ability to specify a type of the input file with the -x switch
Usage example: tcc -xc ex5.cgi
    From a gcc docs:

    You can specify the input language explicitly with the -x option:

    -x language
    Specify explicitly the language for the following input files
    (rather than letting the compiler choose a default based on the file
    name suffix). This option applies to all following input files until
    the next -x option. Possible values for language are:

        c  c-header  c-cpp-output
        c++  c++-header  c++-cpp-output
        objective-c  objective-c-header  objective-c-cpp-output
        objective-c++ objective-c++-header objective-c++-cpp-output
        assembler  assembler-with-cpp
        ada
        f77  f77-cpp-input f95  f95-cpp-input
        java

    -x none
    Turn off any specification of a language, so that subsequent files
    are handled according to their file name suffixes (as they are if -x
    has not been used at all)

tcc -E -P1
  don't follow a gcc preprocessor style and do output a standard

  we going to compile a resulting file wtith a compiler not
  understanding a gnu style line info.

55ea6d3fc1 x86-64 ABI fixes.
abitest now passes; however test1-3 fail in init_test. All other tests
pass. I need to re-test Win32 and Linux-x86.

I've added a dummy implementation of gfunc_sret to c67-gen.c so it
should now compile, and I think it should behave as before I created
gfunc_sret.

e31579b076 Fixed tests on Windows (including out-of-tree problems)
Modified tcctest.c so that it uses 'double' in place of 'long double'
with MinGW since this is what TCC does, and what Visual C++ does. Added
an option -norunsrc to tcc to allow argv[0] to be set independently of
the compiled source when using tcc -run, which allows tests that rely on
the value of argv[0] to work in out-of-tree builds.

Also added Makefile rules to automatically update out-of-tree build
Makefiles when in-tree Makefiles have changed.

762a43877b configure: pass CONFIG_xxxDIR/PATH options via commandline
- except for CONFIG_SYSROOT and CONFIG_TCCDIR

Strictly neccessary it is only for CONFIG_MULTIARCHDIR
because otherwise if it's in config.h it is impossible to
leave it undefined.

But it is also nicer not to use these definitions for
cross-compilers.

05108a3b0a libtcc: new LIBTCCAPI tcc_set_options(TCCState*, const char*str)
This replaces       -> use instead:
-----------------------------------
- tcc_set_linker    -> tcc_set_options(s, "-Wl,...");
- tcc_set_warning   -> tcc_set_options(s, "-W...");
- tcc_enable_debug  -> tcc_set_options(s, "-g");

parse_args is moved to libtcc.c (now tcc_parse_args).

Also some cleanups:
- reorder TCCState members
- add some comments here and there
- do not use argv's directly, make string copies
- use const char* in tcc_set_linker
- tccpe: use fd instead of fp

tested with -D MEM_DEBUG: 0 bytes left

This reverts commit 59e18aee0e.

Therefore, such a change is not appropriate now.

27d38bf23f tcc.c: fix argv index for parse_args
I probably broke that myself earlier.  In any case parse_args
needs to start with index 0 because it is is used also recursively
to expand the shebang command from scripts such as
    #!/usr/local/bin/tcc -run -L/usr/X11R6/lib -lX11
which arrives at tcc as only two argv's
    "tcc" "-run -L/usr/X11R6/lib -lX11"

16202e054f Revert "Use CString to concat linker options"
This reverts commit 1c11b857fe.

On windows, libtcc.c is compiled with ONE_SOURCE and then tcc.c is
linked to it. Thus tcc.c can only use public functions which cstr_* are
not.

2eee100c37 Fix use after free for linker_arg
elements in linker_arg are used in TCCState structure and must thus not

support for the second form so that libtool works with tcc. The way it
is done is to concatenate all -Wl options into one and then pass it to
