* add a DL button + serve the signer certificate file (the one used to
timestamp)
* fix the verification instruction (add -untrusted tsa_cert.pem)
* few CSS tweaks to improve page layout
* disable stdout buffering when logging to stdout
* add 'log_to_syslog' parameter in configuration file to enable/disable
logging to syslog
* add 'log_to_stdout' parameter in configuration file to enable/disable
logging to stdout
slight clean-up and reformatting also (thanks to clang-format new
version)
as TS_RESP_CTX is not thread safe, this commit implement a pool of
TS_RESP_CTX in which a thread can pick one in a thread safe maner.
* implement a ts_resp_ctx_wrapper containing a TS_RESP_CTX and a
lock and bool to mark the availability of the TS_RESP_CTX
* implement the get_ctxw to recover a given TS_RESP_CTX in a thread safe
maner
* adapt the rest of the code to accomodate the new way of doing things
* set the default number of threads to 10 as it's now safe to do so
* add a pid file option on command line + implement it
* make the relative path in conf param relative to the configuration
file directory and not the running directory
as many configuration paths can be relative to the execution working
directory, this directory is recorded at launch time, and the set_params
function does a chdir(<start work dir>); <load conf>; chdir("/") when
it's called.
* pass the size of the query to the create_response function
* implement a serial generator based on random numbers
* fix the creation of the bio for the query content
* add logging for the create_reponse
TODO:
* some REAL memory cleaning...
* split the rfc3161 and the http part
* add a logger function
* add a debugging logger function for the requests
* add a specific handler for rfc3161 request
