Move closer to makeing all convert_string_XXX functions return bool.

This reverts a part of 0189087e25. That one might have fixed the fast path,
but it broke the slow path. convert_string_internal returns 0/-1 despite the
size_t result type and the misleading comment. If you follow the path to
smb_iconv and for example iconv_copy(), you will see that this routine returns
0 even after it copied something.
How to check: Use German locale, and do an smbclient "allinfo" on a file
modified in march (März in German). Notice the "ä". Before 0189087 this printed
correctly, after 0189087 it cut off the fields after the M for März.

As discovered by David Disseldorp <ddiss@suse.de>, convert_string_talloc()
doesn't always return consistent results for a zero length string. The
API states an incoming string must *always* contain the terminating null,
but unfotunately too much code expects passing in a zero source length
to return a null terminated string, so at least ensure we return a
correct null string in the required character set and return the
correct length.
Also ensure we cannot return a zero length for a converted string
(we ensure that the returned buffer is always allocated and zero
terminated anyway) as calling code depends on the fact that returning
true from this function will *always* return a non-zero length (as
it must include the terminating null).

we shouldn't accept bad multi-byte strings, it just hides problems

This code wrote to the full buffer in fstrcpy(), pstrcpy() and other
fixed-length string manipulation functions.
The hope of this code was to find out at run time if we were mixing up
pstring and fstring etc, and to record where this came from. It has a
runtime performance impact (particularly if compiled with
--enable-developer).
It is being removed because of the complexity it adds, and the
distinct lack of bugs that this complexity has been credited in
finding.
The macro-based compile-time checking of string sizes remains.

When pulling non-aligned ucs2 strings, we neglected to add in the
pad byte to the buffer length we've eaten. This caused the device
string in TCONX (which seems to be one of the few places that uses
non-aligned ucs2 strings) to be incorrectly read.
Volker please check.

When called from a library, we don't want to call this, as we may
overwrite some of our calling program's context.

We now use the struct smb_iconv_convenience at the core of all our
iconv code, and use global_iconv_convenience for the callers that
don't specify one.
Andrew Bartlett
These now call the common _m functions that consider UTF16 code points.
This removes the code which will make up a 'lame' table in memory, as
this can just as correctly be handled by running the algorithm at runtime (which is to call toupper() and tolower() on characters < 128).
When used, a top level waf build will always locate the correct table
- in the build tree or outside - due to relinking the installed
binary.

next_codepoint() takes as string in CH_UNIX encoding and returns the
unicode codepoint of the next (possibly multibyte) character of the
input string.
The new next_codepoint_ext() function adds the encoding of the input
string as a parameter. next_codepoint() now only calls next_codepoint_ext()
with CH_UNIX als src_charset argument.
This removes calls to push_*_allocate() and pull_*_allocate(), as well
as convert_string_allocate, as they are not in the common API
To allow transition to a common charcnv in future, provide Samba4-like
strupper functions in source3/lib/charcnv.c
(the actual implementation remains distinct, but the API is now shared)
Andrew Bartlett
This renames push_string in Samba3 into push_string_base and
push_string_check for the two different use cases.
This should allow push_string to be imported from Samba4, using it's
calling conventions.
There was some code in pull_ucs2_base_talloc() to cope with this case which
hadn't been added to pull_ascii_base_talloc(). The older Samba returns non
unicode names which is why you are seeing this codepath being executed.
Unify the logic in pull_ascii_base_talloc() and pull_ucs2_base_talloc().

Here is a patch to allow many subsystems to be re-initialized. The only
functional change I made was to remove the null context tracking, as the memory
allocated here is designed to be left for the complete lifetime of the program.
Freeing this early (when all smb contexts are destroyed) could crash other
users of talloc.

This patch is the second iteration of an inside-out conversion to cleanup
functions in charcnv.c returning size_t == -1 to indicate failure.
