linuxthreads.old: fix nommu initial thread stack detection
Because the nommu address space is flat, and the application stack can
literally be located anywhere, we cannot rely on the assumptions that the
mmu port gets away with. Namely, that the first thread's stack lives at
the top of memory and nothing will be created above it.
Currently, the code rounds the current stack up a page and sets that as
the "top" of the stack, and then marks the "bottom" of the stack as "1".
Then as new threads are created, this assumption is further refined by
slowly backing off the "bottom" when a new stack is created within the
range of the initial stack.
Simple ascii example (tid0 is the initial thread):
1 thread:
[bos tid0 stack tos]
2 threads:
[ tid0 stack ]
[tid1 stack]
3 threads:
[ tid0 stack ]
[tid1 stack]
[tid2 stack]
As you can kind of see, this algorithm operates on one basic assumption:
the initial top of stack calculation is the absolute top of the stack.
While this assumption was fairly safe in the original nommu days of yore
where the only file format was FLAT (which defaults to a 4KiB stack --
exactly 1 page), and memory was fairly tight, we can see that this falls
apart pretty quickly as soon as the initial stack is larger than a page.
The issue that crops up now is simple to hit: start an application with
an 8KiB stack, execute some functions that put pressure on the stack so
that it exceeds 4KiB, then start up some threads. The initial tos will
be rounded up by a page, but this is actually the middle of the stack.
Now when the initial thread returns from its functions (thus unwinding
the stack) and tries to call something which calls back into libpthread,
the thread_self() func fails to detect itself as the initial thread as
the current stack is now above the tos. The __pthread_find_self() func
kicks in, walks all the thread arrays, fails to find a hit, and then
walks into uninitialized memory for the thread descriptor. Use of this
garbage memory has obvious results -- things fall down & go boom.
To address this, I extend the current algorithm to automatically scale
back both the bottom and the top stack limits of the initial thread.
We use the current stack pointer at "thread boot time" only as a single
known point. The initial thread stack bottom is set to the bottom of
memory and the initial thread stack top is set to the top of memory.
Then as we create new stack threads, we figure out whether the new stack
is above or below the single known good address, and then scale back
either the tos or the bos accordingly.

33cb7f0b4 tried to add a small optimization for skipping unnecessary

works for non-fdpic targets (since the type can be cast to an integer), it

When a string format is processed and the argument is NULL, this yields

same behaviour.
Consider the not uncommon case of strings implemented like this:
struct string { int len; char *ptr; };
There is often no nultermination and they may be printed like this:
printf("%.*s", string.len, string.ptr);
If len is 0 then ptr may be anything, but NULL is a common value.

ldso: get rid of _dl_lookup_hash
Now _dl_find_hash and _dl_lookup_hash are exactly the same, we can get rid
of the _dl_lookup_hash, reverting the _dl_find_hash from a wrapper of
_dl_lookup_hash to its original role.

Add protected symbols support for all architectures
Protected symbols are global symbols for which interposition is not allowed.
We manage them in generic _dl_lookup_hash function. To handle protected symbols
we need to get a reference to the module that defines the symbol itself.
So we pass a new parameter 'struct symbol_ref' to the __dl_lookup_hash
that is defined as below:
struct symbol_ref {
const ElfW(Sym) *sym;
struct elf_resolve *tpnt;
};
The tpnt field is used as an ouput parameter and refers to the module which defines
the protected symbol.
Further it can be used as output parameter for TLS relocations and FDPIC case.
The sym field is instead used as an input parameter to detect the visibility of the
symbol we are looking-up.
In this way we get rid of different signatures for _dl_lookup_hash, allowing to remove
the _dl_find_hash wrapper.
This new structure is also suitable for prelink integration.

syslog: fix 'everyone logs with user facility'
It's been found that on uclibc-based system most of the programs log with
'user' facility despite the calls to openlog() with other facilities explicitly
set. Most but not all. Investigating that I've found that the ones logging with
proper facilities used LOG_NDELAY in openlog(). The problem is that LogFacility
is overwritten in openlog_intern and LOG_USER is passed to it from vsyslog() no
matter what the program set with openlog().

The generation of the sysnum.h has to be a prerequisite of

The so called C bootstrap headers are required to build the compiler
by invoking 'make headers', so the 'headers' target cannot relies itself
