* license clarifications. Accidental GPL removed. Introduced by me during
*nix reform in a few .incs and those templates got copied around (os* sysc*)
* clarify OS2/EMX license to actually name the license rather than
saying "NOT GPL" and refering to EMX.

Every startup code must now provide an additional entry point called "_dynamic_start" that is set as new the entry point if the program links to a Pascal shared library. Its purpose is to set up an exit hook usually passed via a register, which should be called during program finalization if non-nil.
We use this additional entry point because this register only has meaningful content when there are any compile-time linked shared libraries, otherwise it often contains random garbage. The difference between the _dynamic_start and the original code is minimal; actually in all implementations the _dynamic_start code passes on control to the old startup code, so we use an additional entry point instead of an additional startup file.
Detailed changes and fixes list:
compiler:
always link to the dynamic loader (ld.so) when compiling shared libraries. Fixes crashes in the loader during shared library finalization on some Linuxes
remove additional ENTRY() section in arm linker script
select either _dynamic_start or _start as entry point depending on whether this is a static or dynamic executable
powerpc*:
do not set System.isLibrary in startup code, it will be set during library initialization anyway
trap in case of reaching code locations that should not be reached instead of looping (possibly endlessly)
powerpc:
register atexit() function pointer if supplied to the executable and call it during shutdown
correctly set argc/argv/envp in shared library code and return correctly to the caller after initialization
pass on exitcode in shared library haltproc
use the more recent exit_group system call if available for shutdown
powerpc64
fix .ptrgl stub, do not set the environment register to the value of the GOT entry in the function descriptor
arm
do not set System.isLibrary in startup code, it will be set during library initialization anyway
reload exitcode to pass to shutdown
mips,mipsel,sparc
added stubs to allow correct linking

and no language features requiring initialization are used,
do not initialize units, but just configure the fpu and
signal handlers.
git-svn-id: trunk@16124 -
unit's initialization code in case we're in a library
+ implemented InquireSignal(), AbandonSignalHandler(), HookSignal() and
UnhookSignal() in the sysutils unit
* for Kylix compatibility, these routines support operating on
SIGINT and SIGQUIT as well, although they are not hooked by default
by FPC. The run time errors/exception codes for these signals are
resp. 217 and 233 (same as in Kylix; I changed ENoWideStringSupport
to 234).
* changed the BSD syscall version of fpsigaction to use pointer
rather than "var" arguments (compatible with other targets, and
required to be able to pass nil arguments inside the system unit)
-> together fixes mantis #12704
