pico_tree_insert: check return value and free memory if needed

Issue #387: Added some more checking/freeing stuff/todos

Issue #387: Check return value of pico_timer_add() and pico_timer_add_hashed()

fixing some errors

fixing pico_tree_insert return value checking (issue #380)

[mDNS] - Added test for re-initing mDNS module when it's fully initialized

[mDNS] - Optional clearing of Cache-tree #382

[mDNS] - Added possibility to re-init mDNS-module should fix #382

[mDNS] - Attempt to fix some TICS-violations

[mDNS] - Make sure loop breaks when first question with conflict name is found. Should fix resource leak detected by Coverty Scan

mdns fix potential memory leak (thanks to TICS)

[mDNS] - WIP - Effort to improve cyclomatic complexity

Make local variables static

detected using -Wmissing-variable-declarations clang option

Enforced style via uncrustify

clean up trailing whitespace (fixes #324)

mDNS code readability : small improvement

Fixed warning

MDNS amount of probing and announcement packets adjusted

RFC 6762: 18.11 compliant

RFC 6762: 18.1 and 18.6 compliant

Cleared up naming in dev_tap, added opcode check in mdns, fixed typo in dns common

Fixed the ambiguous order of operations warning

Fixed failure to set MSB

Error in record_delete

Error in pico_mdns_record_delete

Removed pico_mdns_record_set_class

Fix for #316 dns pico_dns_rdata_cmp should compare bytewise

Added testcase in dns for the rdata comparison concernin lowercase comparison

Revamping timer API to fix #308

Improved C89 compatability (e.g. Watcom compiler)

changed pico_mreq to pico_ip_mreq

pico_ip_mreq is deprecated

[mDNS] - Build fix

[mDNS] - Fixed checked for NULL after deref

[mDNS] - Current TTL of record was not set before inserting in the tree

[mDNS] - 0-length record resulted record->rdata = NULL, which caused unable to find records when destroying mDNS-rtree. Checks for NULL-pointers before inserting in pico_tree added. Fix for #301 and better fix for #300

[DNS_SD] When kv-pair vector is empty, don't bother to try to create and claim a TXT record. This fixes #300

[mDNS] - Removed stdlib-functions

Fix mDNS memleak

mDNS conflict resolution : use '-2', not ' (2)'

mDNS conflicting probes : keep original capitalisation

DNS & mDNS are case insensitive

fix mDNS/DNS-SD memory leaks

Reviewed coding style, preparing for release

[mDNS] - Fix of TICS DEREF-violation

[mDNS] - Wrong setting of name-buflen on reception of record caused issue #285.
This commit fixes #285

Revert "Re-made style"

This reverts commit 8b4a64259d2fbd2db6e64524eebc07aef066f766.

Re-made style

[mDNS] - Removed test-case tc_mdns_record_create_from_dns

[mDNS] - If received records were decompressed, the rname_length field had the wrong length which could cause memory leaks. Also the cause of murphy's law-effect on the demo.

Spell check and change file mode bits of tex files

Made style with uncrustify

[mDNS] - Only constants in preprocessor directives

Some functions need to be static

Fixed "unused variable" warning

[mDNS] - More overall descriptive setting of constant bits

[mDNS] - Overall more descriptive setting of record flags

[mDNS] - More descriptive setting of flags

[mDNS] - Meta-service records are added to MyRecords now.

[mDNS] - Attempt to fix TICS res-leak violation with: copy.

Proper merging of development

Fixed warning introduced in previous commit

Added boundaries to the dns notation change functions

Possible boundaries violations found via Pareon Verify tool.

Fix potential stack overflow in mdns module

Updated Copyright information.

Coding style enforced.

[mDNS] Fix Abstract Interpretation warnings

[(m)DNS] Code refactoring

[mDNS][DNS] Move dup code into common file

[mDNS] Extra dbg prints + new unittests

[mDNS] Fixed issue #198 + unittest for adding cookie to QTable

[mDNS] Added more unittests + cookie lookup fix

- Added a bunch of unittests for the RR cache
- One cookie table related ftn still only looked for url

[mDNS] Proper copying of rdata

- memcpy rather than strdup
- fixes IPv6 address caching

[mDNS] Fix compiler warning

[mDNS] Fix TICS complaint

"Function 'pico_mdns_flush_cache' has no explicit parameter list."

[mDNS] Return upon mem alloc error

[mDNS] Added&Updated unittests

Remove mDNS debug output by default

[mDNS]Param check when adding rr in cache

Fixed some warnings

[mDNS] Added API call to flush mDNS cache

- Added 'pico_mdns_flush_cache()'
- Updated user manual

Upcoming:
- Fix IPv6 address caching issue
- Write unittests for new functions

[mDNS] Improved RR caching

- Don't cache RR when TTL = 0
- Schedule RR deletion when in cache and TTL = 0

Known issue: IPv6 IPs in cache are incorrect

Working mDNS cache + fixed cookie lookup

- cookie lookup also matching qtype now

[mDNS]Initial commit for RR caching

Fix deleting cookie in pico_mdns_timeout

The urls stored in the tree are in the 3www6google2be0 format, but the
name is changed automatically to this format in pico_mdns_del_cookie.
I'm working on a better solution for this.

[mDNS] No DNS timeout tmr for cookie when probing

Revert 2d5a609a36fda2810d4e696555ec4d9514767cc8

- Reverting for now, not a good solution. Problem with add_cookie
unit test code

Cleaned up DNS Client and mDNS modules a little

- Included pico_mdns.h in c file
- Moved flags defines to dns_common
- made mDNS dest address a define

Fixed incorrect pointer in mDNS module

All mDNS unittests pass again

Various small cleanup for (m)DNS

Combine common functions of mDNS and DNS

Functions that are shared by the DNS client and the mDNS client are
combined in pico_dns_common. There is still some overlap between the two
modules, so this should be refactored to make the common part even
bigger.

Esthetical cleanup mdns

Removed some uneccesary blank lines and used return instead of else for
decreasing indentation level.

Enforced coding style via uncrustify

Fixed badly aligned ptr dereference in mdns module
