#106 exported 'list_init' symbol name is too common and conflicts

[othalla]

'list_init' symbol name exported in library is too common and causes runtime symbol conflict. Application crashes, if is linked with any other library exporting 'list_init' symbol. There is no need to export 'list_init' symbol from TSP library if not defined in library API. It should have unique prefix.

There is another conflicting exported symbol 'hash_free'.
Such symbols should not be exported at all... or at least prefixed.
This need to be fixed ASAP.

Some other common symbols to be fixed too (not exported or prefixed):

addEntry
addTable
add_mem_entry
add_pixmap_directory
add_table_entry
audit_set_ordinal_audit_status
build_delegate_public_info

context_free
copy_key_info
copy_key_info2

As an example, on my system the trouSerS-exported constructor "my_init" conflicts with another one defined in the mysqlclient* libraries, therefore any application linking both libtspi and mysql (e.g. php, through GnuTLS) will crash on exit as libtspi's destructor function will be called without the constructor having been called before, because of the name clash.

I want to emphasize the importance of this issue. Fedora is currently expanding the use of this library which causes other applications to crash. I am also wondering why it takes several years to fix a bug like this.

Hi.

Problem here is lack of resources (the human one). I'm currently the
maintainer of TrouSerS, after Kent Yoder and Rajiv Andrade left this
position and I still couldn't track what they did or not to fix the past
bugs. I'm currently working on an important bug, but I'll take some time
to check this issue.

Bug finally fixed. I'll provide another version as soon as I finish with
another bug.
