b0bd6a13ec Fixed argc/argv/envp for arm/linux shared libraries. They are by default in registers a1/a2/a3 as per ABI: the first arguments when calling a method (in this case the FPC_SHARED_LIB_START) are passed via registers, not on the stack.

a8bf34d3fc Correctly return to caller in ARM/Linux shared library startup code instead of fall-through to system exit.

2139a229d3 + If no unit is used, no symbol inside the system unit is used, 
and no language features requiring initialization are used,
    do not initialize units, but just configure the fpu and
    signal handlers.

eda7a8d672 * replaced the "quick exit" instruction sequences from the syscall variants 
lacking "nostackframe" with branches to an exit label, because in that
    case the compiler-generated exit code must be executed to balance the
    stack (only done for EABI; should probably also be done for OABI, but
    I can't test that)

f6d452c2c0 * remove the RTL's installed signal handlers at the end of the system 
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
