hopefully, soon it'll start emitting line number information for i8086-msdos
that is usable by DOS debuggers.

per platform (currently only enabled for win32 and win64). Enabling it forces
code page conversion from the codepage of the .msg file to CP_ACP, before
writing the message to the console. Not enabling it keeps the previous
behaviour of not doing any kind of code page conversion for messages. This
feature should be tested and enabled per platform, because it requires code
page conversion support in the rtl (so it may require adding the appropriate
extra units, such as fpwidestring). When this feature is enabled for all
platforms, we can start keeping only one .msg file per language, because
having extra .msg files for different encodings for the same language becomes
redundant, since the compiler can do code page conversion to whatever code
page the console uses.

sysv_abi_cdecl calling conventions on x86-64 to force using the SYSV/

Note 1: using an older AS might fail anyway if the amount of sections is too high (like in packages\odata\src\sharepoint.pp)
Note 2: it might be an idea to keep track of the created sections in the asmlists and only enable the option if *really* necessary (like with the internal COFF output generator), though this might lead to false positives due to multiple sections with the same name (since I'd prefer to use the KISS principle only a counter would be used)

this should also generate a switch to external assembler.

* the old FPC_SYSTEMMAIN is still in place for bootstrapping
rtl/inc/systemh.inc, TEntryInformation:

Merged revision(s) 28796, 28837-28845, 28847-28850, 28852, 32135 from branches/svenbarth/packages:
Provide possibility to pass packages and search paths for packages as parameters.
fpkg.pas:
+ new unit which contains the base types related to package files (most importantly "tpackage")
globals.pas:
+ new variable "packagesearchpath" which contains all paths in which package files should be looked for
+ new variable "packagelist" which contains a list of all packages that should be used in a program or library
* InitGlobals & DoneGlobals: initialize/finalize "packagesearchpath" accordingly ("packagelist" is handled in unit fpkg using a init/done-callback)
options.pas:
+ TOption: new fields "parapackagepath" and "parapackages" to keep track of package search paths and package files passed as parameters
* TOption.interpret_option: use '-Fp' for package search paths and '-FP' for package files
* read_arguments: apply the passed package search paths and packages to their respective containers
........
+ add a new unit which will contain basic functions related to handling packages
........
Move package related functions from pmodules to pkgutil.
pmodules.pas => pkgutil.pas:
* createimportlibfromexports

........
* adjust indentation
........
Extract the code to export the symbols of a unit to its own function in pkgutil so that less functions need to be exported.

pkgutil.pas:
+ new function export_unit
- remove exports of procexport, varexport and insert_export

Some small fixes for package parsing.
pmodules.pas, proc_package:
* use orgpattern instead of pattern to build the module name (like is done in uses sections)
* ignore duplicates when generating exports
- no need to generate an import library for the package; that is done by the program/library that uses the package
........
+ new unit fpcp of which the class tpcppackage handles the reading and writing of package metadata from/to pcp files (equivalant to tppumodule).
........
+ add unit which contains representation of a PCP file (tpcpfile) like tppufile is for units.
........
Improve export generation.

fppu.pas, tppumodule:
+ new method loadfrompackage which searches all available packages for the unit and loads it from there if found
* loadppu: first try to load the unit from a package if any are available
........
Don't link objects files of a unit that is provided by a package.
pmodules.pas, proc_program:
* if a unit has uf_in_library set we must not include it in the units we link against

how the fpc sections have to be linked *on Linux*. This prevents the
"did you forget -T" warnings from ld, and in general is more correct than
our previous approach of specifying a complete linker script without -T
and hoping that there won't be any unexpected interactions with ld's
built-in linker script (fixed version of r31664, thanks to Alan Modra)
o use the new -X9 command line option to generate linker scripts that
are compatible with binutils older than 2.19 (reverts to the old
behaviour)
