Remove some dynamic exception specifiers.

GCC 11 does not like them, and GCC 2 does not seem to care.

setmime: hash() conflicts with std::hash.

* found with GCC6

include strings.h where appriopriate...

instead or additionally to string.h, in preparation for functions move.
* moves str[n]casecmp() functions and others to strings.h.
* strings.h doesn't include string.h anymore.
* this solves #10949

Fix CID991133: Same if expression was duplicated

Fix init.problem in setmime MimeAttribute ctor

* additional check for empty attribute values introduced;
* implemented copy-ctor and assignment operator for MimeAttribute;
* added missed initialization of parameters in the "UserArgs"
MimeAttribute ctor;
* Fixes #9444.

[Coverity] Restore std::cout flags and MimeAttr ctor. inits

* Restore std::cout flags (CID11245, CID11246) after using hexadecimal
and zero-filled flags;
* Fix uninit MimeAttribute::fStatus field in one ctor. CID11292.

Second part of 'setmime' implementation is completed

* Support for bitmap and vector icons added;
* Attribute type representation is improved;
* Fixed problem with current attributes loading;
* sniffer rule checking fixed;
* supress useless lines in -dumpIcons and -dumpSniffRules for MIME types
without icons and sniffer rules correspondently.

* This tool was created and implemented in draft during GCI 2011
by Aleksas Pantechovskis, <alexp.frl@gmail.com>;
* Later it was heavily refactored and optimized to Haiku Coding
Standards by Siarzhuk Zharski;
* Icons support still missing;
