3a09450fbf Stop calling _init/_fini methods from crt1 for dynamic binaries. Do 
call preinit, init and fini arrays methods from crt1 for static binaries.

Mark new crt1 with FreeBSD-specific ELF note.

Move some common crt1 code into new MI file ignore_init.c, to reduce
duplication.  Also, conservatively adjust nearby sources for style.

12dd9eb8e9 Let all .c and .S files under lib/csu consistently use the __FBSDID() 
macro for identification, instead of several different hand-rolled
variants (plain .ident, .ascii, etc).

b59a09ce79 Properly declare non-extern functions in crt1 
Also move the declarations after __progname consistently to
make the distinction clearer.

26450b90d3 Remove the get_term() function. It pretty much can't work for 
FreeBSD, and makes ugly diffs with the other crt1.c's. Leave
behind a comment (words supplied by Thomas Moestl) that explain
the issue.

bedd05ccec The main reason for this is to reduce diffs between all the crt1.c's. 
Assembler macros are tidied up and made as similar as sanely possible.
The macros are translated into C (__inline static) functions for lint.

Declaration orders are made the same.
Declarations are all ISOfied and tidied up.

Comment contents have gratuitous diffs removed.

The net result is a bunch of crt1.c's that are 90% the same.
It may be possible to now encapsulate the differences in one
MD header, and have only one MI crt1.c file (although the macros
to do this may be ugly).

76fe441a7b Do not use __progname directly (except in [gs]etprogname(3)). 
Also, make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.

3f719eddda Comment out the retrieval of a termination function from %g1. It is 
doubtful this will ever be used by anything and rtld uses %g1.
Comment out references to _init and _fini for now too.

994cab589b Sparc64 ELF version of the C runtime support. 
It tries to comply with the SCD 2.4.1 (and thus Sparc 64-bit psABI).

This is an amalgamation of the FreeBSD Alpha crt1.c and the BSD/OS Sparc
crt0.c (which the copyright reflects).
